LimeSDR setup with GnuRadio

Not where it was built but where it is installed using the make install. In the quoted case above, the source was build using the -DCMAKE_INSTALL_PREFIX=/home/marty/sdr/limesdr/runtime cmake option. The default prefix is /usr/local and in that case it should not be necessary to export the plugin path.

I do not know if it will work without running make install.
