CMake/Modules/FindLua51.cmake
Rolf Eike Beer cfe4ac4b41 use PATH_SUFFIXES to simplify find_* calls
Especially remove "lib64" when the given paths are all Unix ones and "lib" is
also explicitely given. In that case CMake will search "lib64" anyway for
platforms where it is known to make sense.

# Locate Lua library
# This module defines
# 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/
