# Locate the glfw3 library
#
# This module defines the following variables:
#
# GLFW3_LIBRARY the name of the library;
# GLFW3_INCLUDE_DIR where to find glfw include files.
# GLFW3_FOUND true if both the GLFW3_LIBRARY and GLFW3_INCLUDE_DIR have been found.
#
# To help locate the library and include file, you can define a
# variable called GLFW3_ROOT which points to the root of the glfw library
# installation.
#
# default search dirs
#
# Cmake file from: https://github.com/daw42/glslcookbook
