|
|
# Find the OpenGL Extension Wrangler Library (GLEW)
|
|
#
|
|
# IMPORTED Targets
|
|
# ^^^^^^^^^^^^^^^^
|
|
#
|
|
# This module defines the :prop_tgt:`IMPORTED` target ``GLEW::GLEW``,
|
|
# if GLEW has been found.
|
|
#
|
|
# Result Variables
|
|
# ^^^^^^^^^^^^^^^^
|
|
#
|
|
# This module defines the following variables:
|
|
#
|
|
# ::
|
|
#
|
|
# GLEW_INCLUDE_DIRS - include directories for GLEW
|
|
# GLEW_LIBRARIES - libraries to link against GLEW
|
|
# GLEW_FOUND - true if GLEW has been found and can be used
|
