A problem that has been bothering me for 7 months

KaiKai

I want to use the QWebEngine module.

Following the document, I added in CMakeList.txt:

find_package(Qt6 REQUIRED COMPONENTS WebEngineWidgets)
target_link_libraries(target PRIVATE Qt::WebEngineWidgets)

Press F7 to compile, I always get these:

This time, I am sure that I'm using MSVC. And Qt 6.2.4, CMake 3.25.2.

@KaiKai said in A problem that has been bothering me for 7 months:

[cmake] Qt6WebEngineCore could not be found because dependency Qt6Positioning could
[cmake] not be found.

This was in your error log.

To fix it, install the Qt Positioning module.

@JKSH
I will not use the features about location. Could I not import this module?

Qt WebEngine uses that module behind-the-scenes, so you must install it.

@KaiKai said in A problem that has been bothering me for 7 months:

WrapVulkanHeaders

I would recommend you use higher Qt version for example 6.4. Have a look at the bug report about Could NOT find WrapVulkanHeaders (missing: Vulkan_INCLUDE_DIR)
https://bugreports.qt.io/browse/QTBUG-95391

Following this, I fix it! Thanks
