vasilito 1a9d77761e fix(qtdeclarative): properly generate qtquick-config.h features

The qtquick-config.h file was being generated empty by the cmake
build, causing 'division by zero in #if' errors in downstream
consumers (SDDM, KWin) because QT_CONFIG(quick_shadereffect) and
QT_CONFIG(quick_draganddrop) were undefined.

Two fixes:
1. Explicitly enable QT_FEATURE_quick_shadereffect and
   QT_FEATURE_quick_draganddrop in the cmake configuration.
2. Add a safety net that regenerates qtquick-config.h with the
   required feature definitions if cmake produces an empty file.

libxcvt

libxcvt is a library providing a standalone version of the X server implementation of the VESA CVT standard timing modelines generator.

libxcvt also provides a standalone version of the command line tool cvt copied from the Xorg implementation and is meant to be a direct replacement to the version provided by the Xorg server.

An example output is:

$ cvt --verbose 1920 1200 75
# 1920x1200 74.93 Hz (CVT 2.30MA) hsync: 94.04 kHz; pclk: 245.25 MHz
Modeline "1920x1200_75.00"  245.25  1920 2064 2264 2608  1200 1203 1209 1255 -hsync +vsync

Building

libxcvt is built using Meson

$ git clone https://gitlab.freedesktop.org/xorg/lib/libxcvt.git
$ cd libxcvt
$ meson build/ --prefix=...
$ ninja -C build/ install
$ cd ..

Credit

The code base of libxcvt is identical to xf86CVTMode() therefore all credits for libxcvt go to the author (Luc Verhaegen) and contributors of xf86CVTMode() and the cvt utility as found in the xserver repository.
