#[=======================================================================[.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/
