# SYNOPSIS
|
|
#
|
|
# AX_CHECK_GL
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# Check for an OpenGL implementation. If GL is found, the required
|
|
# compiler and linker flags are included in the output variables
|
|
# "GL_CFLAGS" and "GL_LIBS", respectively. This macro adds the
|
|
# configure option "--with-apple-opengl-framework", which users can
|
|
# use to indicate that Apple's OpenGL framework should be used on Mac
|
|
# OS X. If Apple's OpenGL framework is used, the symbol
|
|
# "HAVE_APPLE_OPENGL_FRAMEWORK" is defined. If no GL implementation
|
|
# is found, "no_gl" is set to "yes".
