| # FindGDAL |
| # -------- |
| # |
| # |
| # |
| # Locate gdal |
| # |
| # This module accepts the following environment variables: |
| # |
| # :: |
| # |
| # GDAL_DIR or GDAL_ROOT - Specify the location of GDAL |
| # |
| # |
| # |
| # This module defines the following CMake variables: |
| # |
| # :: |
| # |
| # GDAL_FOUND - True if libgdal is found |
| # GDAL_LIBRARY - A variable pointing to the GDAL library |
| # GDAL_INCLUDE_DIR - Where to find the headers |
| |
| # |
| # $GDALDIR is an environment variable that would |
| # correspond to the ./configure --prefix=$GDAL_DIR |
| # used in building gdal. |
| # |
| # Created by Eric Wing. I'm not a gdal user, but OpenSceneGraph uses it |
| # for osgTerrain so I whipped this module together for completeness. |
| # I actually don't know the conventions or where files are typically |
| # placed in distros. |
| # Any real gdal users are encouraged to correct this (but please don't |
| # break the OS X framework stuff when doing so which is what usually seems |
| # to happen). |
| |
| # This makes the presumption that you are include gdal.h like |
| # |
| #include "gdal.h" |
