# CMake module to search for GeoTIFF library
#
# 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.
