Michael Fabian 'Xaymar' Dirks 19506f1997 cmake: Many fixes and improvements 
* Standalone builds no longer require you to have a compiled version of OBS Studio. Instead the project will now download the last compatible libOBS version from CI and use it for linking.
* The project version now has a tweak field again, which is either 0 or determined by the number of git commits since the last release tag.
* The Install command now properly uses CMAKE_INSTALL_PREFIX instead of INSTALL_DIR.
* Packaging is now done using CPack instead of custom commands.
