It would be nice to be able to configure static and shared library builds.
Similar to zmq's CMakeLists, there should be libczmq.so and libczmq-static.a.

If somebody could hint me how to use zproject, I could try it to solve this.

Currently I am editing CMakeLists.txt manually and in fear of the files beginning line:
