Yes, but if-found (by pkg-config) then the macro itself sets GLU_LIBS
and GLU_CFLAGS, so it doesn't make sense to call AC_CHECK_LIB to change
GLU_LIBS value.

action-if-not-found on the other hand is for cases where your GLU
implementation doesn't provide pkg-config and you want to try to find it
with AC_CHECK_LIB.

I believe you that there could be an issue with building glu demos, but
I guess it's issue in your GLU implementation (whatever that is) and
this change is not correct fix for it - it just happen to help in your
case and breaks other cases.

I agree with Martin here.  Can you replicate the problem using a qemu machine and just oe-core?

I took a deeper look at this today and what I think needs to happen is that in the “if-found” block we need to set glu_enabled=yes.  That way the HAVE_GLU AM_CONDITIONAL is set to yes later in the configure process.  Does that seem right?  I’ll test a patch against my platform.

I have not figured out how to enable GLUT on the QEMU platform so I cannot yet test it there.
