premake-core sysincludedirs does not generate -isystem in xcode

My premake script has sysincludedirs "./libs" which goes under Header Search Paths in the Xcode project setting. The command line output then turns this into -I ./libs.

Found a similar issue with cmake: https://gitlab.kitware.com/cmake/cmake/issues/16795

I fixed this by putting ./libs under System Header Search Paths, which generates -isystem ./libs

Seems reasonable to me, we currently have: includedirs -> USER_HEADER_SEARCH_PATHS sysincludedirs -> HEADER_SEARCH_PATHS

While CMake seems to have: includedirs -> HEADER_SEARCH_PATHS sysincludedirs -> SYSTEM_HEADER_SEARCH_PATHS

Should we match that? Or is USER_HEADER_SEARCH_PATHS correct for includedirs? I'm fairly certain someone went out of their way to change it to USER_... relatively recently, so perhaps it is correct?

Making sysincludedirs points to SYSTEM_HEADER_SEARCH_PATHS seems the correct solution to me.

I do not use XCode, what are the differences between USER_HEADER_SEARCH_PATHS and HEADER_SEARCH_PATHS?
