# 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
