UHD warning on build w/ APT installed GR 3.9.5 #32

Closed cclamb closed 2 years ago

Hey, so I installed GR 3.9.5 via APT on Ubutnu 20.04.4 LTS, and then attempted to build gr-foo from the maint-3.9 branch. When attempting to configure via cmake, I get this:

CMake Warning at CMakeLists.txt:73 (find_package):
  By not providing "FindUHD.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "UHD", but
  CMake did not find one.

  Could not find a package configuration file provided by "UHD" with any of
  the following names:

    UHDConfig.cmake
    uhd-config.cmake

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

-- UHD library not found, no support for timed TX.

UHD is installed:

libgnuradio-uhd3.9.5/focal,now 3.9.5.0-0~gnuradio~focal-1 amd64 [installed,automatic]
  gnuradio universal hardware driver functions

Seems like the correct library to use with GR 3.9.5:

Seems to build fine after this warning. Is this really a problem?

What you would need to enable this feature is libuhd-dev but it's nor required.
