Lua is an embedded language, the typical use is to build the source
together with your main program, so in most cases you don't need the
dynamic lib.

In most cases you will add/remove features to the embedded language so
it isn't quite useful to distribute a "generic" dynamic lib and the
Lua should in most cases distributed as sources instead of binaries.

I've attached a CMakeLists.txt which should help you build the dynamic
lib on Linux. If you know how to use cmake and you have a working
Linux system it should work for you.
