wxlua and wxWidgets

[drahosp]

Add wxLua and wxWidgets dependency. http://wxlua.sourceforge.net/
For now dependency will be binary for Windows and a placeholder for other systems.

The easy way out is to just call the existing native build files from cmake rather than trying to translate these fully to cmake. On Windows, this is probably (cd build/msw/ && nmake -f makefile.vc) on MSVC or makefile.gcc on MinGW. On others it would be the autoconf build. Either use execute_process or maybe the more correct thing is ExternalProject_Add.

This is actually a good idea. In this regard LuaDist would act similarly to Homebrew and use the native builds and patch things if needed. I'll try this approach on libgd and wxWidgets. I'd love to avoid binaries as much as possible.

Initial version in Repository, for now Windows only.

Closing this in order to meet the milestone. I will work on the non-windows install with the issue closed.
