CMake Warning (dev) at /usr/local/Cellar/cmake/3.17.3/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:272 (message):
  The package name passed to `find_package_handle_standard_args` (PkgConfig)
  does not match the name of the calling package (Lua).  This can lead to
  problems in calling code that expects `find_package` result variables
  (e.g., `_FOUND`) to follow a certain pattern.
Call Stack (most recent call first):
  /usr/local/Cellar/cmake/3.17.3/share/cmake/Modules/FindPkgConfig.cmake:45 (find_package_handle_standard_args)
  cmake/FindLua.cmake:39 (include)
  CMakeLists.txt:539 (find_package)
