From 2c4a5319bfa6086ae7ba4119ef05094dc03a2a5c Mon Sep 17 00:00:00 2001 From: Stuart Mentzer Date: Mon, 5 Sep 2016 12:18:46 +0100 Subject: [PATCH] Final version of FindFreetype.cmake that is based on the now-accepted CMake patches. This supports the new freetype include path structure and fixes the failure to find the debug library on Windows due to its name having a 'd' suffix. --- CMakeModules/FindFreetype.cmake | 188 ++++++++++++++++++++++++++++++++ 1 file changed, 188 insertions(+) create mode 100644 CMakeModules/FindFreetype.cmake diff --git a/CMakeModules/FindFreetype.cmake b/CMakeModules/FindFreetype.cmake new file mode 100644 index 000000000..f24372b34 --- /dev/null +++ b/CMakeModules/FindFreetype.cmake @@ -0,0 +1,188 @@ +#.rst: +# FindFreetype +# ------------ +# +# Locate FreeType library +# +# This module defines +# +# :: +# +# FREETYPE_LIBRARIES, the library to link against +# FREETYPE_FOUND, if false, do not try to link to FREETYPE +# FREETYPE_INCLUDE_DIRS, where to find headers. +# FREETYPE_VERSION_STRING, the version of freetype found (since CMake 2.8.8) +# This is the concatenation of the paths: +# FREETYPE_INCLUDE_DIR_ft2build +# FREETYPE_INCLUDE_DIR_freetype2 +# +# +# +# $FREETYPE_DIR is an environment variable that would correspond to the +# ./configure --prefix=$FREETYPE_DIR used in building FREETYPE. + +#============================================================================= +# Copyright 2000-2016 Kitware, Inc. +# Copyright 2000-2011 Insight Software Consortium +# All rights reserved. +# +# Redistribution and use in source and binary forms, with or without +# modification, are permitted provided that the following conditions +# are met: +# +# * Redistributions of source code must retain the above copyright +# notice, this list of conditions and the following disclaimer. +# +# * Redistributions in binary form must reproduce the above copyright +# notice, this list of conditions and the following disclaimer in the +# documentation and/or other materials provided with the distribution. +# +# * Neither the names of Kitware, Inc., the Insight Software Consortium, +# nor the names of their contributors may be used to endorse or promote +# products derived from this software without specific prior written +# permission. +# +# THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS +# "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT +# LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR +# A PARTICULAR PURPOSE ARE DISCLAIMED.
