+FindGDAL
+--------
+
+Find Geospatial Data Abstraction Library (GDAL).
+
+IMPORTED Targets
+^^^^^^^^^^^^^^^^
+
+This module defines :prop_tgt:`IMPORTED` target ``GDAL::GDAL``
+if GDAL has been found.
+
+Result Variables
+^^^^^^^^^^^^^^^^
+
+This module will set the following variables in your project:
+
+``GDAL_FOUND``
+ True if GDAL is found.
+``GDAL_INCLUDE_DIRS``
+ Include directories for GDAL headers.
+``GDAL_LIBRARIES``
+ Libraries to link to GDAL.
+``GDAL_VERSION``
+ The version of GDAL found.
+
+Cache variables
+^^^^^^^^^^^^^^^
+
+The following cache variables may also be set:
+
+``GDAL_LIBRARY``
+ The libgdal library file.
+``GDAL_INCLUDE_DIR``
+ The directory containing ``gdal.h``.
+
+Hints
+^^^^^
+
+Set ``GDAL_DIR`` or ``GDAL_ROOT`` in the environment to specify the
+GDAL installation prefix.
+#]=======================================================================]
+
# $GDALDIR is an environment variable that would
# correspond to the ./configure --prefix=$GDAL_DIR
# used in building gdal.
