Great. I just took a stab at redrafting the new FAQ material for clarity, not accuracy. So now I will ask, is what's described actually correct, at least for Linux and GCC? http://www.cmake.org/Wiki/CMake_FAQ#Library_questions If it's all YMMV for different Unixes or compilers, then we need strong warnings about trying to apply this trick cross-platform. As well as performance consequences you mention.
