# --------
#
# Find the GLFW library.
#
# Imported targets
# ^^^^^^^^^^^^^^^^
#
# This module defines the following :prop_tgt:`IMPORTED` target:
#
# ``Glfw::Glfw``
# The Glfw library, if found.
#
# Result variables
# ^^^^^^^^^^^^^^^^
#
# This module will set the following variables in your project:
#
# ``GLFW_INCLUDE_DIRS``
# where to find GLFW/glfw3.h, etc.
# ``GLFW_LIBRARIES``
# the libraries to link against to use Glfw.
# ``Glfw_FOUND``
# If false, do not try to use Glfw.
