# Locate Lua library | ||
# This module defines | ||
# LUA52_FOUND, if false, do not try to link to Lua | ||
# LUA_LIBRARIES | ||
# LUA_INCLUDE_DIR, where to find lua.h | ||
# LUA_VERSION_STRING, the version of Lua found (since CMake 2.8.8) | ||
# | ||
# 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/ | ||
