[waffle] [PATCH] RFC: add FindWAFFLE.cmake

[groleo at gmail.com]

From: Adrian Marius Negreanu <adrian.m.negreanu at intel.com>

Problem:
piglit searches waffle by using pkg_check_modules.
If one tried to use cmake and android toghether,
waffle won't be found, since pkg_check_modules relies on
pkg-config(missing on android)

Proposed fix:
add a Module file so that find_package can be used
instead of pkg_check_modules.

+# - Find the native WAFFLE includes and library
+#
+# This module searches libpng, the library for working with WAFFLE images.
+#
+# It defines the following variables
+#  WAFFLE_INCLUDE_DIRS, where to find png.h, etc.
+#  WAFFLE_LIBRARIES, the libraries to link against to use WAFFLE.
+#  WAFFLE_DEFINITIONS - You should add_definitons(${WAFFLE_DEFINITIONS}) before compiling code that includes png library files.
+#  WAFFLE_FOUND, If false, do not try to use WAFFLE.
+# Also defined, but not for general use are
+#  WAFFLE_LIBRARY, where to find the WAFFLE library.
+# For backward compatiblity the variable WAFFLE_INCLUDE_DIR is also set. It has the same value as WAFFLE_INCLUDE_DIRS.
+#
+# Since WAFFLE depends on the ZLib compression library, none of the above will be
+# defined unless ZLib can be found.
