Locate Lua library.
|
||
|
|
This module defines::
|
||
|
|
|
||
|
|
::
|
||
|
|
|
||
|
|
LUA50_FOUND, if false, do not try to link to Lua
|
||
|
|
LUA_LIBRARIES, both lua and lualib
|
||
|
|
LUA_INCLUDE_DIR, where to find lua.h and lualib.h (and probably lauxlib.h)
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
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/
|
