build: include our libraries before system libraries (#21746)

Browse Source 
Including our libraries as system libraries is helpful to suppress any
warnings, but the default behavior is to include it after existing
libraries. This can become a problem with some package managers such as
macports, as CMake automatically adds /opt/local to the include path,
which is where they store all includes. This means that the wrong header
might be chosen if it has the same name as the one from our
dependencies.

Adding the BEFORE keyword when including will ensure that our
dependency headers are chosen first.

Also remove old Darwin workarounds that shouldn't be necessary anymore.
