   1 # Locate gdal
   2 #
   3 # This module accepts the following environment variables:
   4 #
   5 #    GDAL_DIR or GDAL_ROOT - Specify the location of GDAL
   6 #
   7 # This module defines the following CMake variables:
   8 #
   9 #    GDAL_FOUND - True if libgdal is found
  10 #    GDAL_LIBRARY - A variable pointing to the GDAL library
  11 #    GDAL_INCLUDE_DIR - Where to find the headers
  12 #
  13 # $GDALDIR is an environment variable that would
  14 # correspond to the ./configure --prefix=$GDAL_DIR
  15 # used in building gdal.
  16 #
  17 # Created by Eric Wing. I'm not a gdal user, but OpenSceneGraph uses it
  18 # for osgTerrain so I whipped this module together for completeness.
  19 # I actually don't know the conventions or where files are typically
  20 # placed in distros.
  21 # Any real gdal users are encouraged to correct this (but please don't
  22 # break the OS X framework stuff when doing so which is what usually seems
  23 # to happen).
  24
  25 # This makes the presumption that you are include gdal.h like
  26 #
