+####################################################################################################
+#
+# This is a build system used by platform maintainers to build library dependencies on
+# Windows and macOS. There is some support for Linux as well, but not ready for releases.
+#
+# Windows and macOS users should download the precompiled libraries in lib/, Linux users
+# should run install_deps.sh for building dependencies.
+#
+# WINDOWS USAGE:
+#   Don't call this cmake file your self, use build_deps.cmd
+#   build_deps 2013 x64 / build_deps 2013 x86
+#   build_deps 2015 x64 / build_deps 2015 x86
+#
+# MAC OS X USAGE:
+#	Install with homebrew: brew install autoconf automake libtool yasm openssl xz
+#   Run "make deps" from main Blender directory
+#
+# LINUX USAGE:
+#   Install compiler, cmake, autoconf, automake, libtool, yasm
+#   Run "make deps" from main Blender directory

+#
+# It also supports non-standard names for the library components.
+#
+# To use a custom OpenEXR
+#   - Set the variable OPENEXR_CUSTOM to True
+#   - Set the variable OPENEXR_CUSTOM_LIBRARY to the name of the library to
+#     use, e.g. "SpiIlmImf"
+#   - Optionally set the variable OPENEXR_CUSTOM_INCLUDE_DIR to any
+#     particularly weird place that the OpenEXR/*.h files may be found
+#   - Optionally set the variable OPENEXR_CUSTOM_LIB_DIR to any
+#     particularly weird place that the libraries files may be found
+#
+# This module defines the following variables:
+#
+# OPENEXR_INCLUDE_DIR - where to find ImfRgbaFile.h, OpenEXRConfig, etc.
+# OPENEXR_LIBRARIES   - list of libraries to link against when using OpenEXR.
+#                       This list does NOT include the IlmBase libraries.
+#                       These are defined by the FindIlmBase module.
