# - Find mpg123
# Find the native mpg123 includes and library
#
# MPG123_INCLUDE_DIR - where to find mpg123.h
Overhaul CMakeLists to conform with modern CMake - Prefer target properties instead of setting variables whenever possible. A zmusic-obj target now exists to represent the commonality between zmusic and zmusiclite. - Factored out as much as possible from global settings to per target settings which will make it easier to support using ZMusic as a submodule. Moved helper functions into a ZUtility.cmake module. - We now generate and install ZMusicConfig.cmake so find_package(ZMusic) will work either automatically or given ZMusic_DIR is set. - CPack is enabled although some refinement is still needed. - Requires CMake >= 3.13 which is newer than I would normally like, but given how no one like to refactor these things it may be better to deal with the short term pain of going a little aggressive on the requirement in order to avoid having to make things ugly. Especially given that these scripts have a tendency to be copy/pasted into sister projects. CMake itself has very few dependencies so users of old Linux distros should be able to easily compile a supported version of CMake. - On Windows CMake >= 3.15 is required for redistributable results. - Cleaned out bits that were copied from GZDoom but not relevant to ZMusic.
