# 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"
