[CMake] Recompile with different flags

[Adam Weiss]

I thought only LINK_FLAGS could be added there, I'll try it when I get
back to my work machine.

As for ignoring the flags, I don't think that will work since several files have

#ifndef VAR_NAME
<code>
#else
<code>
#endif

Again, this method bothers me, but I'm supposed to make a few code
changes as possible.

Thanks
