Review MacPorts integration

[scheibel]

It seems like glbinding is available using MacPorts (https://trac.macports.org/ticket/52910).

Tasks:

• Review if installing glbinding via MacPorts works as expected
• Reverse engineer process and artifacts required steps for a MacPorts integration, integrate findings into Templates for integration into external package managers cmake-init#43

see PR #215 as well. As I wrote the portfile and patch for macports, I can probably help you out with this is you need help.

So what y'all need to concentrate on are: (1) installing cmake files into hopefully an externally-specifiable directory; and (2) the *-config.cmake file working for (a) the target itself; (b) in-tree targets (for example, test-cpplocate); and (c) out-of-tree targets (for example: glbinding, when using cpplocate). I just attached updates that fix the *-config.cmake to search a little more robustly ... but, allowing some externally-specifiable directory would be even better.

Closing this for now, as the integration to macports seems stale.
