| CMake module to search for GEOS library | ||
| This module defines: | ||
| If it's found it sets GEOS_FOUND to TRUE | ||
| and the following target is added | ||
| GEOS_INCLUDE_DIR, where to find geos.h, etc. | ||

| GEOS_LIBRARY, libraries to link against to use GEOS. Currently there are | ||
| two looked for, geos and geos_c libraries. | ||
| find_package(GEOS CONFIG) | ||
|
|
||
| GEOS_FOUND, True if found, false if one of the above are not found. | ||
| For ossim, typically geos will be system installed which should be found; | ||
| or found in the ossim 3rd party dependencies directory from a geos build | ||
| and install. If the latter it will rely on CMAKE_INCLUDE_PATH and | ||
| CMAKE_LIBRARY_PATH having the path to the party dependencies directory. | ||
| if(NOT GEOS_FOUND) | ||
|
|
||
| NOTE: | ||
| This script is specialized for ossim, e.g. looking in /usr/local/ossim. | ||
