Alex Neundorf b01184022b Use absolute path to FindPackageHandleStandardArgs.cmake everywhere
This is to avoid getting an (older) copy of FPHSA.cmake which is
e.g. installed with KDE 4.5.0 and 4.5.1.

# 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
#
#include "gdal.h"
