0.26 didn't have the workaround that determine if you're running
OpenGL ES or OpenGL.

the configure script uses pkg-config utility to determine what the
various configuration of the packaged installed. Here it seems that
pkg-config is either not configure properly or doesn't know about Qt.

As such, the configure scripts considers that Qt doesn't have OpenGL
support and doesn't activate it...

If you do have pkg-config installed and configure, you should check
the Qt package so it properly sets pkg-config information
