Did you install it in the same prefix as gnuradio was installed in ?

Not sure where your GR install comes from ...

Are you sure you compiled GLFW3 (and not the 2.x series) ?
And compiled it as a shared library ?

And for opencl, is /usr/lib64/nvidia in the LD_LIBRARY_PATH or in
/etc/ld.so.conf (or similar for your distro).
Maybe it's not meant to be used directly and you should call it
through the ICD ?  Fedora seems to have an opencl-icd package, is that
installed ?
