-# FindPROJ4
-# --------
-#
-# Find the proj includes and library.
-#
-# IMPORTED Targets
-# ^^^^^^^^^^^^^^^^
-#
-# This module defines :prop_tgt:`IMPORTED` target ``PROJ4::proj``,
-# if Proj.4 has been found.
-#
-# Result Variables
-# ^^^^^^^^^^^^^^^^
-#
-# This module defines the following variables:
-#
-# ::
-#
-# PROJ4_INCLUDE_DIRS - where to find proj_api.h, etc.
-# PROJ4_LIBRARIES - List of libraries when using libproj.
-# PROJ4_FOUND - True if libproj found.
-#
-# ::
-#
-# PROJ4_VERSION - The version of libproj found (x.y.z)
-# PROJ4_VERSION_MAJOR - The major version of libproj
-# PROJ4_VERSION_MINOR - The minor version of libproj
-# PROJ4_VERSION_PATCH - The patch version of libproj
-# PROJ4_VERSION_TWEAK - always 0
-# PROJ4_VERSION_COUNT - The number of version components, always 3
-#
-# Hints
-# ^^^^^
-#
-# A user may set ``PROJ4_ROOT`` to a libproj installation root to tell this
-# module where to look exclusively.
