Catkin_make error: No such file or directory of a customized header file

edit

Hello,

I encountered a catkin_make error and already spent several days of trying to solve it but I could not make it. I hope you guys have any ideas on this. I am using Ubuntu 14.04 and ROS Indigo version.

The error message I got when doing catkin_make is

fatal error: AA/AAA.hpp: No such file or directory, which is placed in a header file I made (BBB.hpp as in the below) with #include <AA/AAA.hpp>.

The following is how my source folder is organized roughly.

/devel
/build
/src
    CMakeLists.txt
    /A
        /AA
            CMakeLists.txt
            package.xml
            /src
                AAA.cpp
            /include
                AAA.hpp
    /B
        /BB
            CMakeLists.txt
            package.xml
            /src
                BBB.cpp
            /include
                BBB.hpp

A and B are directories that include corresponding multiple packages in each of them. What I have basically been trying to do is to use functions of AA package from BB package. Therefore, BB package's CMakeLists.txt and package.xml files include necessary parts to work with AA package. In the bottom, I also attached brief structure of CMakeLists of both A and B.

The weird thing is when I included #include <AA/AAA.hpp> in BBB.cpp file, it worked fine. However, when included in BBB.hpp file, I got the above error, which is fatal error: AA/AAA.hpp: No such file or directory. The followings are CMakeLists of A and B. Do you guys have any insights on this? I need to define #include <AA/AAA.hpp> in BBB.hpp file. I really appreciate your help in advance!
