    Better error message when Lua submodule is missing · 1aa809a1

    If CAMPVIS_BUILD_LIB_LUA was set but the Lua Git submodule wasn't checked
    out, the user would get a generic "could not find CMakeLists.txt" error
    message which wasn't of much help.
    Log a custom error message that provides a hint how to fix the problem in
    the above situation.
