Of course I have separate projects. I didn't write libz... Did you?
DLLs should be *shared*. There shouldn't be a need for me to copy them
to my app dir.

Of course you build in separate dirs. Doesn't mean you have to install
into separate dirs.

I don't see why. There's plenty of platform-specific behaviour.

That's exactly the reason it should be done by CMake!
Developers shouldn't have to worry about such platform specifics.

You mean copy/pasting is easy? It's also bad...
Code duplication!
