Used vcproj2cmake[1] (github mirror[2]) as a starting point, and then
added libxmp as a submodule and hacked up the CMakeLists until it was able to
successfully cross-compile on Linux via mingw. (Side note, I was using the
master branch of vcproj2cmake, but apparently there are several more recent
branches, including experimental_unverified which has more than 1000(!)
additional commits...)
Could definitely stand to get rid of more cruft in the recipe, esp since
we almost certainly won't be autogenerating the cmake stuff from the vcproj
going forward. Could even rewrite it from scratch instead, if someone
wanted to.
As such, this is definitely not in a state where it's ready to stand on its
own, lmao
