Possible arguments: (none), XY, XY+, -XY, XY-ZA, module, flavors, build, run, env

Adds a dependency on Lua. By default this is a library dependency, unless overridden by the build and/or run option. The env option prevents the addition of any dependency, while still defining all the usual variables.

The default version is set by the usual DEFAULT_VERSIONS mechanism, unless a version or range of versions is specified as an argument, for example, 51 or 51-53.

Applications using Lua are normally built for only a single Lua version. However, library modules intended to be loaded by Lua code should use the module option to build with multiple flavors.
