Can CLion find headers files with a CMake custom toolchain ?

Hello,
I set up a new project and I use a custom CMake toolchain that I specify in CMake options. Everything is working fine and the project builds, but CLion seems not to find the headers specified using target_include_directories. That is annoying because all the editor functionalities are not available, and everywhere in my program, parts of code are red. Is there a way to add the include directory to the "header search paths" or do anything else to solve the problem?
Thanks.
