# The following function is defined:
#
# add_latex_document(<tex_file>
# [BIBFILES <bib_files>]
# [INPUTS <input_tex_files>]
# [IMAGE_DIRS <image_directories>]
# [IMAGES <image_files>]
# [CONFIGURE <tex_files>]
# [DEPENDS <tex_files>]
# [MULTIBIB_NEWCITES <suffix_list>]
# [USE_BIBLATEX]
# [USE_INDEX]
# [INDEX_NAMES <index_names>]
# [USE_GLOSSARY] [USE_NOMENCL]
# [FORCE_PDF] [FORCE_DVI] [FORCE_HTML]
# [TARGET_NAME <name>]
# [INCLUDE_DIRECTORIES <directories>]
# [EXCLUDE_FROM_ALL]
# [EXCLUDE_FROM_DEFAULTS])
# Adds targets that compile <tex_file>. The latex output is placed
# in LATEX_OUTPUT_PATH or CMAKE_CURRENT_BINARY_DIR if the former is
# not set. The latex program is picky about where files are located,
# so all input files are copied from the source directory to the
# output directory. This includes the target tex file, any tex file
# listed with the INPUTS option, the bibliography files listed with
# the BIBFILES option, and any .cls, .bst, .clo, .sty, .ist, and .fd
# files found in the current source directory. Images found in the
# IMAGE_DIRS directories or listed by IMAGES are also copied to the
# output directory and converted to an appropriate format if necessary.
# Any tex files also listed with the CONFIGURE option are also processed
# with the CMake CONFIGURE_FILE command (with the @ONLY flag). Any file
# listed in CONFIGURE but not the target tex file or listed with INPUTS
# has no effect. DEPENDS can be used to specify generated files that are
# needed to compile the latex target.
#
# The following targets are made. The name prefix is based off of the
# base name of the tex file unless TARGET_NAME is specified. If
# TARGET_NAME is specified, then that name is used for the targets.
#
# name_dvi: Makes <name>.dvi
# name_pdf: Makes <name>.pdf using pdflatex.
# name_safepdf: Makes <name>.pdf using ps2pdf. If using the
# default program arguments, this will ensure all fonts
# are embedded and no lossy compression has been
# performed on images.
# name_ps: Makes <name>.ps
# name_html: Makes <name>.html
# name_auxclean: Deletes <name>.aux and other auxiliary files.
# This is sometimes necessary if a LaTeX error occurs
# and writes a bad aux file. Unlike the regular clean
# target, it does not delete other input files, such as
# converted images, to save time on the rebuild.
#
# Unless the EXCLUDE_FROM_ALL option is given, one of these targets
# is added to the ALL target and built by default. Which target is
# determined by the LATEX_DEFAULT_BUILD CMake variable. See the
# documentation of that variable for more details.
#
# Unless the EXCLUDE_FROM_DEFAULTS option is given, all these targets
# are added as dependencies to targets named dvi, pdf, safepdf, ps,
# html, and auxclean, respectively.
#
# USE_BIBLATEX enables the use of biblatex/biber as an alternative to
# bibtex. Bibtex remains the default if USE_BIBLATEX is not
# specified.
#
# If the argument USE_INDEX is given, then commands to build an index
# are made. If the argument INDEX_NAMES is given, an index file is
# generated for each name in this list. See the LaTeX package multind
# for more information about how to generate multiple indices.
#
# If the argument USE_GLOSSARY is given, then commands to
# build a glossary are made. If the argument MULTIBIB_NEWCITES is
# given, then additional bibtex calls are added to the build to
# support the extra auxiliary files created with the \newcite command
# in the multibib package.
#
# INCLUDE_DIRECTORIES provides a list of directories in which LaTeX
# should look for input files. It accepts both files relative to the
# binary directory and absolute paths.
#
# The <name>_dvi and <name>_pdf targets have a property named
# COMPILER_FLAGS. The text in this property is added as flags to the
# latex and pdflatex commands, respectively.
#
# History:
#
# 2.8.1 Replace use of the deprecated exec_program with execute_process.
#
# 2.8.0 Add COMPILER_FLAGS property to *_dvi and *_pdf targets. Setting
# the property will add flags to the LaTeX compilation (in addition
# to any flags provided by CMake cache variables).
#
# 2.7.2 Add CONFIGURE_DEPENDS option when globbing files to better detect
# when files in a directory change. This only happens for CMake 3.12
# or better.
#
# 2.7.1 Fix issues with printing log on errors when there are spaces in the
# path. (Thanks to Peter Knowles.)
#
# Ignore LaTeX warning about the font shape series value `mc'.
#
# 2.7.0 Add INCLUDE_DIRECTORIES parameters. (Thanks to Eric Dönges.)
#
# 2.6.1 Fix issue with detecting long undefined reference warnings that
# LaTeX "helpfully" split across lines (and which fowled up our
# regex).
#
# 2.6.0 Skip image conversion targets that are not used when a force option
# is given. This helps prevent errors for missing conversion programs
# that are not needed. (Thanks to Martin Wetzel.)
#
# 2.5.0 Parse biber output for warnings.
#
# For regular bibtex, you get warnings about undefined references
# when you run latex. However, when using biber, biber itself prints
# out the said warning and latex sees nothing. Thus, when using biber
# the regular output is now suppressed and the log file is scanned
# for potential issues.
#
# 2.4.9 Use biblatex.cfg file if it exists and the USE_BIBLATEX option is ON.
#
# 2.4.8 Fix synctex issue with absolute paths not being converted.
#
# 2.4.7 Fix some issues with spaces in the path of the working directory where
# LaTeX is executed.
#
# 2.4.6 Fix parse issue with older versions of CMake.
#
# 2.4.5 Fix issues with files and paths containing spaces.
#
# 2.4.4 Improve error reporting message when LaTeX fails.
#
# When LaTeX fails, delete the output file, which is invalid.
#
# Add warnings for "missing characters." These usually mean that a
# non-ASCII character is in the document and will not be printed
# correctly.
#
# 2.4.3 Check for warnings from the natbib package. When using natbib,
# warnings for missing bibliography references look different. So
# far, natbib seems to be quiet unless something is important, so
# look for all natbib warnings. (We can change this later if
# necessary.)
#
# 2.4.2 Fix an issue where new versions of ImageMagick expect the order of
# options in command line execution of magick/convert. (See, for
# example, http://www.imagemagick.org/Usage/basics/#why.)
#
# 2.4.1 Add ability to dump LaTeX log file when using batch mode. Batch
# mode suppresses most output, often including error messages. To
# make sure critical error messages get displayed, show the full log
# on failures.
#
# 2.4.0 Remove "-r 600" from the default PDFTOPS_CONVERTER_FLAGS. The -r flag
# is available from the Poppler version of pdftops, but not the Xpdf
# version.
#
# Fix an issue with the flags for the different programs not being
# properly separated.
#
# Fix an issue on windows where the = character is not allowed for
# ps2pdf arguments.
#
# Change default arguments for latex and pdflatex commands. Makes the
# output more quiet and prints out the file/line where errors occur.
# (Thanks to Nikos Koukis.)
#
# After a LaTeX build, check the log file for warnings that are
# indicative of problems with the build.
#
# Remove support for latex2html. Instead, use the htlatex program.
# This is now part of TeX Live and most other distributions. It also
# behaves much more like the other LaTeX programs. Also fixed some
# nasty issues with the htlatex arguments.
#
# 2.3.2 Declare LaTeX input files as sources for targets so that they show
# up in IDEs like QtCreator.
#
# Fix issue where main tex files in subdirectories were creating
# invalid targets for building HTML. Just disable the HTML targets in
# this case.
#
# 2.3.1 Support use of magick command instead of convert command for
# ImageMagick 7.
#
# 2.3.0 Add USE_BIBLATEX option to support the biblatex package, which
# requires using the program biber as a replacement for bibtex
# (thanks to David Tracey).
#
# 2.2.1 Add STRINGS property to LATEX_DEFAULT_BUILD to make it easier to
# select the default build in the CMake GUI.
#
# 2.2.0 Add TARGET_NAME option.
#
# 2.1.1 Support for finding bmp, ppm, and other image files.
#
# 2.1.0 Fix an error where the pdf target and others were defined multiple
# times if UseLATEX.cmake was included multiple times.
#
# Added INDEX_NAMES option to support multiple indexes in a single
# document from the multind package (thanks to Dan Lipsa).
#
# 2.0.0 First major revision of UseLATEX.cmake updates to more recent features
# of CMake and some non-backward compatible changes.
#
# Changed all function and macro names to lower case. CMake's identifiers
# are case insensitive, but the convention moved from all upper case to
# all lower case somewhere around the release of CMake 2. (The original
# version of UseLATEX.cmake predates that.)
#
# Remove condition matching in if statements. They are no longer necessary
# and are even discouraged (because else clauses get confusing).
#
# Use "new" features available in CMake such as list and argument parsing.
#
# Remove some code that has been deprecated for a while.
#
# Mark variables for compiler and converter executables as advanced to
# match the more conventional CMake behavior.
#
# Changed how default builds are specified and add the ability to force
# a particular build.
#
# Made the base targets (pdf, dvi, etc.) global. add_latex_document
# always mangles its target names and these base targets depend on
# the targets with mangled names.
#
# 1.10.5 Fix for Window's convert check (thanks to Martin Baute).
#
# 1.10.4 Copy font files to binary directory for packages that come with
# their own fonts.
#
# 1.10.3 Check for Windows version of convert being used instead of
# ImageMagick's version (thanks to Martin Baute).
#
# 1.10.2 Use htlatex as a fallback when latex2html is not available (thanks
# to Tomasz Grzegurzko).
#
# 1.10.1 Make convert program mandatory only if actually used (thanks to
# Julien Schueller).
#
# 1.10.0 Added NO_DEFAULT and DEFAULT_PS options.
# Fixed issue with cleaning files for LaTeX documents originating in
# a subdirectory.
#
# 1.9.6 Fixed problem with LATEX_SMALL_IMAGES.
# Strengthened check to make sure the output directory does not contain
# the source files.
#
# 1.9.5 Add support for image types not directly supported by either latex
# or pdflatex. (Thanks to Jorge Gerardo Pena Pastor for SVG support.)
#
# 1.9.4 Fix issues with filenames containing multiple periods.
#
# 1.9.3 Hide some variables that are now cached but should not show up in
# the ccmake list of variables.
#
# 1.9.2 Changed MACRO declarations to FUNCTION declarations. The better
# FUNCTION scoping will hopefully avoid some common but subtle bugs.
# This implicitly increases the minimum CMake version to 4.6 (although
# I honestly only test it with the latest 4.8 version).
#
# Since we are updating the minimum CMake version, I'm going to start
# using the builtin LIST commands that are now available.
#
# Favor using pdftops from the Poppler package to convert from pdf to
# eps. It does a much better job than ImageMagick or ghostscript.
#
# 1.9.1 Fixed typo that caused the LATEX_SMALL_IMAGES option to fail to
# activate.
#
# 1.9.0 Add support for the multibib package (thanks to Antonio LaTorre).
#
# 1.8.2 Fix corner case when an argument name was also a variable containing
# the text of an argument. In this case, the CMake IF was matching
# the argument text with the contents of the variable with the same
# argument name.
#
# 1.8.1 Fix problem where ps2pdf was not getting the appropriate arguments.
#
# 1.8.0 Add support for synctex.
#
# 1.7.7 Support calling xindy when making glossaries.
#
# Improved make clean support.
#
# 1.7.6 Add support for the nomencl package (thanks to Myles English).
#
# 1.7.5 Fix issue with bibfiles being copied two different ways, which causes
# Problems with dependencies (thanks to Edwin van Leeuwen).
#
# 1.7.4 Added the DEFAULT_SAFEPDF option (thanks to Raymond Wan).
#
# Added warnings when image directories are not found (and were
# probably not given relative to the source directory).
#
# 1.7.3 Fix some issues with interactions between makeglossaries and bibtex
# (thanks to Mark de Wever).
#
# 1.7.2 Use ps2pdf to convert eps to pdf to get around the problem with
# ImageMagick dropping the bounding box (thanks to Lukasz Lis).
#
# 1.7.1 Fixed some dependency issues.
#
# 1.7.0 Added DEPENDS options (thanks to Theodore Papadopoulo).
#
# 1.6.1 Ported the makeglossaries command to CMake and embedded the port
# into UseLATEX.cmake.
#
# 1.6.0 Allow the use of the makeglossaries command. Thanks to Oystein
# S. Haaland for the patch.
#
# 1.5.0 Allow any type of file in the INPUTS lists, not just tex file
# (suggested by Eric Noulard). As a consequence, the ability to
# specify tex files without the .tex extension is removed. The removed
# function is of dubious value anyway.
#
# When copying input files, skip over any file that exists in the
# binary directory but does not exist in the source directory with the
# assumption that these files were added by some other mechanism. I
# find this useful when creating large documents with multiple
# chapters that I want to build separately (for speed) as I work on
# them. I use the same boilerplate as the starting point for all
# and just copy it with different configurations. This was what the
# separate ADD_LATEX_DOCUMENT method was supposed to originally be for.
# Since its external use is pretty much deprecated, I removed that
# documentation.
#
# 1.4.1 Copy .sty files along with the other class and package files.
#
# 1.4.0 Added a MANGLE_TARGET_NAMES option that will mangle the target names.
#
# Fixed problem with copying bib files that became apparent with
# CMake 2.4.
#
# 1.3.0 Added a LATEX_OUTPUT_PATH variable that allows you or the user to
# specify where the built latex documents to go. This is especially
# handy if you want to do in-source builds.
#
# Removed the ADD_LATEX_IMAGES macro and absorbed the functionality
# into ADD_LATEX_DOCUMENT. The old interface was always kind of
# clunky anyway since you had to specify the image directory in both
# places. It also made supporting LATEX_OUTPUT_PATH problematic.
#
# Added support for jpeg files.
#
# 1.2.0 Changed the configuration options yet again. Removed the NO_CONFIGURE
# Replaced it with a CONFIGURE option that lists input files for which
# configure should be run.
#
# The pdf target no longer depends on the dvi target. This allows you
# to build latex documents that require pdflatex. Also added an option
# to make the pdf target the default one.
#
# 1.1.1 Added the NO_CONFIGURE option. The @ character can be used when
# specifying table column separators. If two or more are used, then
# will incorrectly substitute them.
#
# 1.1.0 Added ability include multiple bib files. Added ability to do copy
# sub-tex files for multipart tex files.
#
# 1.0.0 If both ps and pdf type images exist, just copy the one that
# matches the current render mode. Replaced a bunch of STRING
# commands with GET_FILENAME_COMPONENT commands that were made to do
# the desired function.
#
# 0.4.0 First version posted to CMake Wiki.
