dnl
|
|
dnl Check for GLU. If GLU is found, the required preprocessor and
|
|
dnl linker flags are included in the output variables "GLU_CFLAGS" and
|
|
dnl "GLU_LIBS", respectively. This macro adds the configure option
|
|
dnl "--with-apple-opengl-framework", which users can use to indicate
|
|
dnl that Apple's OpenGL framework should be used on Mac OS X. If
|
|
dnl Apple's OpenGL framework is used, the symbol
|
|
dnl "HAVE_APPLE_OPENGL_FRAMEWORK" is defined. If no GLU implementation
|
|
dnl is found, "no_glu" is set to "yes".
