+# 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

+# 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
