I think what you are looking for is lua_get_shared_lib() from

Knowing the library name only helps if I patch the build system; that's
what I'm getting at. The few packages where this works use CMake, and
CMake already tries to guess[0] the name of the lua library (thanks
Debian) and so it has a pre-defined variable to store the result.
Not all build systems are going to work like that. Suppose I know that
the name of the lua library is "lua5.2". An autotools build system is
going to run something like,
AC_SEARCH_LIBS([whatever], [lua], [lua_found="yes"])
How do I pass the name "lua5.2" to that, without hacking configure.ac
and running autoreconf? The only option that comes to mind is to build
the entire project with LIBS="-llua5.2", but that's not right if only
some of the executables are supposed to be linked with lua.
For contrast, if the lua library was stored in /usr/lib64/lua5.2, then I
could just set LIBS="-L/usr/lib64/lua5.2" and let ./configure do its thing.
