The source uses CMake for compiling the program.

I provided the compile.sh script that can help in this phase.

You can modify CMakeLists.txt for switch some compilation option ON/OFF:

Allow to use libsidplay2 (actually the only supported library: library must to be patched with cia1.patch for working):
option (WITH_SIDPLAY2 "UseSidplay2 library" ON) 

Allow to use TSID library:
option (WITH_TSID "Use TSID library" ON)

Allow to use TSID2 library:
option (WITH_TSID2 "Use TSID2 library" ON)

Allow to have some debug information printed to console:
set (XSID_WB_DEBUG 1)
set (XSID_SDL_DEBUG 1)
set (XSID_ALSA_DEBUG 1)
set (XSID_PLAYER_DEBUG 1)
