#[=======================================================================[.rst:
FindLuaJIT
-------
Locate LuaJIT library.
This module defines:
``LUAJIT_FOUND``
if false, do not try to link to LuaJIT
``LUAJIT_LIBRARIES``
both luajit and luajitlib
``LUAJIT_INCLUDE_DIR``
where to find lua.h
``LUAJIT_VERSION_STRING``
the version of LuaJIT found
``LUAJIT_VERSION_MAJOR``
the major version of LuaJIT
``LUAJIT_VERSION_MINOR``
the minor version of LuaJIT
``LUAJIT_VERSION_PATCH``
the patch version of LuaJIT
Note that the expected include convention is
::
#include "lua.h"
and not
::
#include <lua/lua.h>
This is because, the lua location is not standardized and may exist in
locations other than lua/
