Cmake가 Qt5WebEngineWidgets 모듈을 찾을 수 없습니다.

QSyncthingTray를 컴파일하고 싶습니다(https://github.com/sieren/QSyncthingTray) 내 노트북에서 아치 리눅스 x86을 실행하고 있습니다.

$QTDIR을 다음으로 설정했습니다.

/home/user/.qt/5.5/gcc/

및 $CMAKE_PREFIX_PATH

$Qt5WebEngineWidgets_DIR을 다음과 같이 설정하기도 했습니다.

/home/user/.qt/5.5/gcc/lib/cmake/Qt5WebEngineWidgets

디렉터리가 존재하고 필요한 파일이 그 안에 있습니다.

Cmake가 여전히 오류가 발생했습니다.
