[libmodplug] Fails to compile on Debian 9, probably all Linux

Okay, so trying to compile libmodplug (a dependency of sdl2-mixer) appears to be failing on Linux:

The following packages will be built and installed:

Upon looking at the log file, it was endless swaths of errors like:

I think I know what's going on here. The CMakeLists.txt included in libmodplug does not appear to be designed to work under *NIX, as I also could not get the program to compile myself using it - instead I encountered the exact same errors.

Instead, I had to resort to autotools. The bundled INSTALL file is incorrect, as there is no configure script included in the git repository. Instead, one must autoreconf it yourself. Thus:

$ autoreconf -vi
$ ./configure
$ make

However, I haven't the faintest clue how to properly integrate these build steps into vcpkg.
