[PATCH] lib/xtrx: add missing libraries

[Gwenhael Goavec-Merou]

When using gr-osmosdr with an xtrx board

Executing: /usr/bin/python3 -u /home/gwe/sources/nop.py

ImportError: /usr/lib/libgnuradio-osmosdr.so.0.2.0: undefined symbol: xtrx_tune_rx_bandwidth

libgnuradio-osmosdr has no references to libxtrx*.so*:
$ ldd /usr/lib/libgnuradio-osmosdr.so.0.2.0.0 | grep xtrx
$

After adding the mandatory library in CMakeLists.txt, flowgraph start
correctly:

Executing: /usr/bin/python3 -u /home/gwe/sources/nop.py

And the libgnuradio-osmosdr is correctly linked to libxtrx*.so*
$ ldd /usr/lib/libgnuradio-osmosdr.so.0.2.0.0 | grep xtrx
        libxtrx.so.0 => /usr/local/lib/libxtrx.so.0 (0x00007f0cf7188000)

        libxtrxdsp.so.0 => /usr/local/lib/libxtrxdsp.so.0 (0x00007f0cf6526000)
