Qt Creator: "This Qt Version does not contain Qt Quick compiler"

[Maash]

Hi.

I started making some QML changes and noticed that it's not built on my package. Then I looked into project qmake settings, and it's not possible to enable Qt Quick compiler. I installed the LGPL licensed QT package last week:

Based on Qt 5.5.1 (GCC 4.9.1 20140922 (Red Hat 4.9.1-10), 64 bit)

I tried installing the Qt Quick with apt-get (Ubuntu 15.04), but it didn't really change anything. I cannot really change the Qt plugin directory to ubuntu as it doesn't seem to work properly (see issue: https://forum.qt.io/topic/61374/missing-xcb-plugin-in-ubuntu-15-04)

Any ideas would be appreciated!

Isn't "Qt Quick compiler" a commercial product you have to pay for?

I must admit that I'm new to Qt in general, but I was under impression that you could do QML stuff under LGPL license.

Yes, you can do QML and QtQuick for free. But the Qt Quick Compiler is not free. It is not needed, it can be used to "compile" QML stuff to improve performance, but QML works without this compiler as well.
