CMake failed to load QWebWidgets module

SGaist

Excuse me to insist but: which compiler are you using ?

This?

@KaiKai This is CMake, not compiler. Please show what compiler you're using.

KaiKai

@jsulm Or this? (I'm sorry, I'm only a newbie)

@KaiKai Ell, you could also simply show what compiler is set in the Kit, but from the last screen-shot it is at least visible that you're using MinGW. To use WebEngine you have to use Microsoft compiler (because the used Google Chromium engine only supports Microsoft compiler). So, you have to install Microsoft Visual Studio (or build tools) and Qt for Microsoft compiler.

@jsulm I have changed the compiler to MSVC. Everything else has been successful, but CMake has not found this module so far.

@KaiKai Did you install QtWebView module for Qt/MSVC?

KaiKai

@jsulm I've installed WebEngine and WebView module in Qt Maintenance Tool.

I met the same error as you did. And it seems that the reason of my situation is because:

WebEngineWidgets has a WebEngineCore dependency
but WebEngineCore cannot find its Positioning dependency.

Therefore, after I install "Qt Positioning" module in Qt Maintainance Tools, the error disappeared.

@Haowei-Hsu you saved my day ^^. Thank you. Qt Positioning really fix this issue on my Qt 6.8
