# On success, the macro sets the following variables:
# GEOTIFF_FOUND = if the library found
# GEOTIFF_LIBRARIES = full path to the library
# GEOTIFF_INCLUDE_DIR = where to find the library headers also defined,
# but not for general use are
# GEOTIFF_LIBRARY = where to find the PROJ.4 library.
# GEOTIFF_VERSION = version of library which was found, e.g. "1.2.5"
