New description:

 This port is failing to build for 10.15 and earlier, due to needing to
 build with a 2017 cxx compiler.

 From the project `CMakeLists.txt`:

 {{{
 set(CMAKE_CXX_STANDARD 17)
 set(CMAKE_CXX_STANDARD_REQUIRED ON)
 }}}

 In addition, there are also failures for earlier macOS releases, due to a
 requirement on `CLOCK_REALTIME`. The latter is currently pending via the
 following PR, and `legacysupport` should be added once a new release is
 available with this functionality:
