# SYNOPSIS
|
|
#
|
|
# AX_CHECK_GLUT
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# Check for GLUT. If GLUT is found, the required compiler and linker flags
|
|
# are included in the output variables "GLUT_CFLAGS" and "GLUT_LIBS",
|
|
# respectively. If GLUT is not found, "no_glut" is set to "yes".
|
|
#
|
|
# If the header "GL/glut.h" is found, "HAVE_GL_GLUT_H" is defined. If the
|
|
# header "GLUT/glut.h" is found, HAVE_GLUT_GLUT_H is defined. These
|
|
# preprocessor definitions may not be mutually exclusive.
