OpenSceneGraph/CMakeModules/FindGDAL.cmake
Robert Osfield 6f2d003bc5 From Mattias Helsing, "Seems I was only half right given what you asked for. CMP0017 only
says that modules that are found and ran from cmake modules dir should
prefer cmake-provided modules. find_package() and include() still look
in CMAKE_MODULE_PATH first.

After some investigating I've come up with a proposal examplified in
the attached FindGDAL.cmake script. It simply calls the cmake provided
FindGDAL.cmake if it exists and returns if it succeeds in finding GDAL
using that, otherwise continue with our local cmake code.
Pro: Wont clutter our root CMakeLists.txt
Con: If we begin to write more advanced Findxxx modules (using
COMPONENTS, REQUIRED etc.) we may have to revise this scheme.

# Locate gdal
# This module defines
# GDAL_LIBRARY
# GDAL_FOUND, if false, do not try to link to gdal
# 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"
