It's still has some work, but it successfully builds on
all 3 main platforms. Some of the outstanding items
include:
Install target testing (mostly important for Linux)
CMakeList clean up and comments
Debug and Release build verification
Audit of compile/link options
Need a Mac signed and notarized build
(and probably more)
It appeared to be usable on Windows but still wasn't flexible. I've
updated it with commands based on the autotools configs and now
filedialog can be built on linux, macos and freebsd using cmake.
Previously lib-src that we controlled had their cmake files with them. This is clearer.
Also added place holders for help and locale.
Also enabled libvorbis and soundtouch and disabled portburn.
