# Custom Visual Studio project generation logic that supports any platform that has a msvs.py
# script, so Visual Studio can be used to run scons for any platform, with the right defines per target.
# Invoked with scons vsproj=yes
#
# Only platforms that opt in to vs proj generation by having a msvs.py file in the platform folder are included.
# Platforms with a msvs.py file will be added to the solution, but only the current active platform+target+arch
# will have a build configuration generated, because we only know what the right defines/includes/flags/etc are
# on the active build target.
#
# Platforms that don't support an editor target will have a dummy editor target that won't do anything on build,
# but will have the files and configuration for the windows editor target.
#
# To generate build configuration files for all platforms+targets+arch combinations, users can call
# scons vsproj=yes
# for each combination of platform+target+arch. This will generate the relevant vs project files but
# skip the build process. This lets project files be quickly generated even if there are build errors.
#
# To generate AND build from the command line:
# scons vsproj=yes vsproj_gen_only=no
