find lua executables with suffix. eg. fails to find something like 'lua53.exe'
This should be refactored so luacom module isn't dumped into global space but one step at a time.
Added compatibility code so luacom can still build under Lua 5.1
than matching against lua headers.

There was a problem hiding this comment.
Just wanted to mention, for some reason Lua 5.1 seems to output the version string to stderr. At least that's the case for me under Win7. That's the reason for setting ERROR_VARIABLE to lua_version_str here, in case the interpreter splits out the version string to stderr, cmake will capture it.

Did some various fixes particular to CMake detection so it can better find later versions of Lua as well as LuaJIT.
Also had to fix some of the lua C calls carryover from pre Lua 5.2, like
luaL_registerandlua_strlen. I knowLUA_COMPAT_MODULEcan be defined for backwards compatibility but it assumes that the lua runtime hasluaL_openlibcompiled in (luaL_registeris a#defineintoluaL_openlib. I ran into linking issues since my runtime didn't have it.It seems to make more sense to just make luacom use the latest Lua C api and put any compatibility code in LuaCompat.* to smooth out version differences. It helps reduce
#ifdeflitter into other source files.Last thing, added a rockspec file that uses cmake to build since it's already in the project.
