#327 we made the defaulut cmake build system use cmake detected generator and release build for rocks.

That if fine for module users.

But as a module developer, after a few days of using the new cmake build system, I found that the follow command line option for luarocks make is required:

Choose Debug build from command line

luarocks make --debug

or

luarocks make --config debug

which is better?

As make command is for developer, should debug be the default for make command
and release default for build command?

Overwrite the default generator for cmake

On Mac, it generate Makefile, but I want Xcode project to debug.

• add options like luarocks make --pass-args "-G Xcode" (should be a better option name)
• or something in ~/.luarocksrc.lua ?
• or maybe I did wrong thing that removed the support of cfg.cmake_generator in Better cmake support. #327 ?

I just currently can't find the best answer myself.
