1# Locate Lua library
2# This module defines
3# LUA_EXECUTABLE, if found
4# LUA_FOUND, if false, do not try to link to Lua
5# LUA_LIBRARIES
6# LUA_INCLUDE_DIR, where to find lua.h
7# LUA_VERSION_STRING, the version of Lua found (since CMake 2.8.8)
8#
9# Note that the expected include convention is
10# #include "lua.h"
11# and not
12# #include <lua/lua.h>
13# This is because, the lua location is not standardized and may exist
14# in locations other than lua/
