Could you share your patch?

I put in absolute paths for QMAKE_LIBS_OPENGL, and then at the end of
my debug statements print out the correct value. However, this
generates a file,
in which I find
QMAKE_LIBS_OPENGL = /lib64/libGL.so
and the build creates a largely redundant
also containing the wrong information, and the build
still links in the system /lib64/libGL.so.
So then I comment out that line in qtbase/src/gui/qtgui-config.pri
before starting the build. The second file,
is now correct, and the build proceeds correctly.
So it seems that it comes down to an incorrectly generated
qtbase/src/gui/qtgui-config.pri, which I can fix post-facto, but I think
must be a better fix. Perhaps your patch?
