CMake Error at CMakeLists.txt:4 (cmake_minimum_required):
  Compatibility with CMake < 3.5 has been removed from CMake.

  Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
  to tell CMake that the project requires at least <min> but has been updated
  to work with policies introduced by <max> or earlier.

  Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.

Unfortunately, homebrew does not respect CMAKE_POLICY_VERSION_MINIMUM=3.5 when set via environment variable and there seems to be no way to specify cmake flags directly with for homebrew.

Therefore, we now switch to the limesuite version from the default homebrew repo. However, this version is way more recent than the other one so API incompatibilities are possible. Tests are passing though, that's a good sign.
