# Locate Lua library

# LUA51_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/
