This looks like a horrible GCC specific hack.  Why should such a thing
be in the FAQ?  I would think the FAQ should contain advice that's
good CMake practice and works cross-platform with all the compilers.
Let's distinguish between "Frequently" Asked Questions and general
repositories of tips and tricks tricks.  There are other sections of
the wiki where you could put a GCC-specific trick.

http://www.cmake.org/Wiki/CMake_FAQ is a wiki so yes you could
personally update it.  But I think others should weigh in about
whether or not you should.

Well they're actually going to do cross-platform work with compilers
other than GCC, they can't rely on GCC behavior to solve all their
problems.  So dealbreak away.  Politically, do they know they actually
need MSVC support?  Or are they in the "gee we're Unix, why CMake?"
stage.  There's nothing you can do about the latter unless you have a
pressing need or desire for cross-platform support.
