CMake Error at CMakeLists.txt:87 (find_package):
  By not providing "FindGnuradio.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Gnuradio",
  but CMake did not find one.

  Could not find a package configuration file provided by "Gnuradio"
  (requested version 3.9) with any of the following names:

    GnuradioConfig.cmake
    gnuradio-config.cmake

  Add the installation prefix of "Gnuradio" to CMAKE_PREFIX_PATH or set
  "Gnuradio_DIR" to a directory containing one of the above files.  If
  "Gnuradio" provides a separate development package or SDK, be sure it has
  been installed.

귀찮아서(!) wayland에서 x.org로 변경후 실행

[링크 : https://mokhwasomssi.tistory.com/427]

UHD :USRP source에서 RTL-SDR source로 바꾸고 일단 실행하니

먼가 그래프로 나오긴 한데.. LoRa가 없어서 지금은 머가 나오는진 모르겠다.
