Qt Creator failing to find Qt headers in working cmake+Qt project

I've installed Qt from Qt's online installer in Ubuntu 16.04, and I am using Qt Creator to work on a cmake+Qt project. The Qt project links to the Qt versions installed by Qt's online installer by setting the path to the Qt library through the CMAKE_PREFIX_PATH variable.

Although the Qt Creator manages to build the project without any problem, Qt Creator is unable to find any Qt headers, listing every #include statement as "No such file or directory" and failing to run any autocompletion on Qt code.

Does anyone know how to get Qt Creator to find Qt headers in a cmake+Qt project?

Does anyone know how Qt Creator determines where are Qt's source code in a cmake project?

Hi,

It's determined by the Kit used.

What version of Qt Creator are you using ?

@SGaist I'm using Qt Creator 4.6.2.

Did you check your kit for any errors ?
