Once it is documented, we can remove the mark_as_advanced.

Original code in the README removed in https://github.com/robotology/robotology-superbuild/pull/31 :

| ROBOTOLOGY_USES_LUA | Include software and plugins that depend on the Lua scripting language. | OFF | Documentation on Lua dependency. |

Lua

Support for this dependency is enabled by the ROBOTOLOGY_USES_LUA CMake option.

Another existing problem (cc @xEnVrE) is that at the moment the setup.sh ( https://github.com/robotology/robotology-superbuild/blob/master/cmake/template/setup.sh.in ) and all related files in Windows (see https://github.com/robotology/robotology-superbuild/issues/147) do not set the LUA_CPATH env variable, so you will need to set it manually.

@Nicogene probably experienced a regression as this option is not tested in CI:
