CMake: include a directory into parent from within a subdirectory (aka library)

Question

I have a small project with this structure:

myproject/ mylib/ include/ src/ myprog/ include/ src/

I added a CmakeLists.txt file into myproject and added the subdirectory mylib and myprog. The subdirectories got a CMakeLists, too. Now, when I run cmake, both modules are built correctly, unless I want to use mylib in myprogram. I've found solutions where the global CmakeLists defines an include_directories. But I would prefer to define this in mylib such that mylib/include is added to the project' include path. I would like a project of submodules where each submodule defines it's sources and includes and the project's CMakeLists only connects the modules together. How can I do that? Is that what I try to achieve recommanded? (cmake newbie)

You want target_include_directories. See http://www.cmake.org/cmake/help/v3.0/manual/cmake-buildsystem.7.html
