Nice to hear that.

And another update to my previous answer.

If your module depends on kernel library (as I understand now it
should be linked to module) you'd better use

target_link_libraries(module1 kernel)

https://cmake.org/cmake/help/v3.4/command/target_link_libraries.html

This dependency also should be resolved first and add kernel library
to linker command.
