[CMake] cmake on mac to generate xcode project

[Anders Sandholm]

Hi

small question. I am using cmake on mac and generate xcode project
with it, but when I generate the project fil it is place in the
directory where the source code i located, and I want to specify
another directory where I want the project file (like the output
directory on windows), can I do this? I check the docs and wiki but
couldn't find anything.

best regards
Anders
