Code navigation jumps to wrong file of same base name

 In brief, when I ctrl+left-click on a function declaration, it jumps to function definition in a wrong file with same base name, class name and function name, whereas the jump target file is out of current project.

My project have this kind of directory layout:

• root
  • ProductA
    • CMakeLists.txt
    • foo.h
    • foo.cpp
  • ProductB
    • CMakeLists.txt
    • foo.h
    • foo.cpp

Files "foo.h" and "foo.cpp" in both project have function with same signature.

If I have open history for both projects, then "Follow symbol under cursor" in a function declaration in ProductB's foo.h, it will jump to ProductA's foo.cpp.

I also tried rename ProductA folder to something else, then re-run cmake for ProductB. Interestingly it sticks to jump to nonexisting ProductA's foo.cpp and failed.

It seems the code model is keeping a global cache somewhere, but indexing symbols only using source file's base name?
