CppCheck include paths

Question

As my application grows I have to add new directories for CppCheck to check. Why is my CppCheck able to find all files in subdirectories for the src/ folder but not for the include folder? I have to add each include folder manually.

stage('CppCheck') {
            steps {
                dir("${env.WORKSPACE}/${FOLDERS_TO_SCAN}"){                 
                    sh label: '', returnStatus: true, script: 'cppcheck --check-config --inline-suppr -itest/ -Iinclude/utilities -Iinclude/ src/ cppcheck --enable=all --suppress=missingIncludeSystem . --inconclusive --xml --xml-version=2 graphal 2> cppcheck-result.xml'
                }
            }   
        }
