[srslte-users] Ettus B205-mini not being detected

[Paul Sutton]

Hi Amir,
You can see in the cmake output that UHD isn't found on the system. This is
why your usrp isn't found by srsUE.
If UHD is installed in a non-standard location, you can export the
environment variable UHD_DIR to help cmake to pick it up. Rebuild srsLTE &
srsUE and make sure UHD is picked up correctly.

Regards,
Paul
