Thanks, that helped! Now I could compile it manually and know that I did install the zmq correctly.

With the help of this CMake Module: https://github.com/Kitware/Remus/blob/master/CMake/FindZeroMQ.cmake
I could make it work with my CMakeLists.txt.

These are the critical lines:

# Define where to find modules for ZeroMQ

The rest is just standard setting include dirs and linking libraries:

include_directories(include ${ZeroMQ_INCLUDE_DIRS})
target_link_libraries(${PROJECT_NAME} ${ZeroMQ_LIBRARIES})
