Thanks for the review.

But what is the CMAKE_BUILD_TYPE in this case? Also, how do you deal with 
these platform issues (Win32 / Win64 / cross-compiles / ...) currently?

I'm not sure what this means. (Keep in mind that I have only ever used the 
UnixMakefiles and Ninja generators).

Do you mean you want to run cmake once and then build multiple 
configurations (at the same time?)?

Instead of what I do which would be 

mkdir debug && cd debug
cmake .. -DCMAKE_BUILD_TYPE=Debug
make
mkdir ../release && cd ../release
cmake .. -DCMAKE_BUILD_TYPE=Release
make

You want to build debug and release at the same time?

Thanks,

Steve.
