# Find GLFW
# ---------
#
# Finds the GLFW library using its cmake config if that exists, otherwise
# falls back to finding it manually. This module defines:
#
# GLFW_FOUND - True if GLFW library is found
# GLFW::GLFW - GLFW imported target
#
# Additionally, in case the config was not found, these variables are defined
# for internal usage:
#
# GLFW_LIBRARY - GLFW library
# GLFW_DLL_DEBUG - GLFW debug DLL on Windows, if found
# GLFW_DLL_RELEASE - GLFW release DLL on Windows, if found
# GLFW_INCLUDE_DIR - Root include dir
#
#
# This file is part of Magnum.

# GLFW installs cmake package config files which handles dependencies in case

# loud messages when it's not found, since that's okay. If the glfw target
# already exists, it means we're using it through a CMake subproject -- don't
# attempt to find the package in that case.
