You need to edit your Qt Creator .pro file to add the path to your header files by modifying the INCLUDEPATH variable. You will probably also have to modify the LIBS variable to add the path and names of the external libraries. After you edit the .pro file, you will have to run qmake or do a clean rebuild in Qt Creator.

See the qmake documentation here (https://doc.qt.io/qt-5/qmake-variable-reference.html).
