#.rst:
# 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.
