Make command failing

[Justin White]

Good Morning Everyone.

I am trying to follow this page https://github.com/tapparelj/gr-lora_sdr
and am running into an odd problem that I just can not seem to get past.

I am currently running the following:
Ubuntu 20.04.4
GNU Radio 3.9

*workcomp*:*~/lora_sdr/gr-lora_sdr/build*$ cmake ../

CMake Warning (dev) at
/usr/lib/x86_64-linux-gnu/cmake/gnuradio/GnuradioConfig.cmake:36 (if):
  if given arguments:

    "ON"

  An argument named "ON" appears in a conditional statement.  Policy CMP0012
  is not set: if() recognizes numbers and boolean constants.  Run "cmake
  --help-policy CMP0012" for policy details.  Use the cmake_policy command to
  set the policy and suppress this warning.
Call Stack (most recent call first):
  CMakeLists.txt:137 (find_package)
This warning is for project developers.  Use -Wno-dev to suppress it.

CMake Warning (dev) at cmake/Modules/GrTest.cmake:45 (get_target_property):
  Policy CMP0026 is not set: Disallow use of the LOCATION target property.
  Run "cmake --help-policy CMP0026" for policy details.  Use the cmake_policy
  command to set the policy and suppress this warning.

  The LOCATION property should not be read from target "test-lora_sdr".  Use
  the target name directly with add_custom_command, or use the generator
  expression $<TARGET_FILE>, as appropriate.

Call Stack (most recent call first):
  lib/CMakeLists.txt:92 (GR_ADD_TEST)
This warning is for project developers.  Use -Wno-dev to suppress it.

I tried to search the archive first, but did not come across this. I
apologize ahead of time if I missed it.

Thank you for any help you may be able to provide.

Best regards,
