cmake include full directory paths

I have a project which is the following:

project/
├── apps
│   ├── app_a
│   ├── app_b
│   ├── app_c
│   ├── CMakeLists.txt
├── CMakeLists.txt
├── common
│   ├── some_data.cpp
│   ├── some_data.h
│   ├── some_data_a
│   ├── some_data_b
│   ├── some_data_c
└── └── CMakeLists.txt

I would like to include directory common which contains some_data.h(cpp) and directories some_data_* which named targets some_data_a, some_data_b, some_data_c.

In root CMakeLists.txt I tried to add:

include_directories(${PROJECT_SOURCE_DIR})

So, it works. For example in my app_a/src/app_a.h I can write include like this:

#include "common/some_data_a/some_data_a.h"

The problem is that I don't understand how to rewrite include_directories from main CMakeLists.txt to common/CMakeLists.txt using target_include_directories? (not just include_directories, I want to delete that string from main CMakeLists.txt).

It is important that I can still able to include the full path. For example in file apps/app_a/app_a.h:

#include "common/some_data_a/some_data_a.h"

not just:

#include "some_data_a/some_data_a.h"

I also tried to write it like this:

target_include_directories(common INTERFACE ${PROJECT_SOURCE_DIR})

But it doesn't work

Solution. Just put this in common/CMakeLists.txt:

target_include_directories(common INTERFACE ${CMAKE_CURRENT_SOURCE_DIR}/..)

And add common to target_link_libraries in some_data_a/CMakeLists.txt
