Yes, the error message told you which one: "features.xkbcommon && libs.xcb". 
Since you have installed the XCB libraries, you should check for xkbcommon 
ones.

If you have libxcb1-dev installed, why are you passing -qt-xcb? And, for that 
matter, why -qt-zlib? Just use your distro's packages for those.
