I'm trying to build under opensuse tumbleweed but i'm getting this error during configure:

[  212s] configure: error: The skins2 module depends on the Qt interface. Without it you will not be able to open any dialog box from the interface, which makes the skins2 interface rather useless. Install the Qt development package or alternatively you can also configure with: --disable-qt --disable-skins2.

The build was going fine before but something has changed in source that causes this error. btw, this the spec file that Iuse for buiding : vlc.spec
