I want to compile "qt-everywhere-src-5.15.0" and especially QtWebEngine native on a Raspberry Pi 4. I make a build directory and go in it, to use the following command:

sudo ../qt-everywhere-src-5.15.0/configure -v -opengl es2 -device linux-rasp-pi4-v3d-g++ -device-option CROSS_COMPILE=/usr/bin/ -opensource -confirm-license -optimized-qmake -reduce-exports -release -qt-pcre -make libs -prefix /usr/local/qt5pi -sysroot / -pkg-config -skip qtscript -skip qtandroidextras -skip qtmacextras -skip qtpurchasing -skip qtwinextras -skip qtcanvas3d  -developer-build

The config.summary was ok:

Qt WebEngine Build Tools:
  Use System Ninja ....................... yes
  Use System Gn .......................... no
  Jumbo Build Merge Limit ................ 8
  Developer build ........................ yes
  QtWebEngine required system libraries:
    fontconfig ........................... yes
    dbus ................................. yes
    nss .................................. yes
    khr .................................. yes
    glibc ................................ yes
  QtWebEngine required system libraries for qpa-xcb:
    x11 .................................. yes
    libdrm ............................... yes
    xcomposite ........................... yes
    xcursor .............................. yes
    xi ................................... yes
    xtst ................................. yes
  Optional system libraries used:
    re2 .................................. no

    png .................................. yes
    JPEG ................................. yes
    harfbuzz ............................. yes
    freetype ............................. yes
    xkbcommon ............................ yes

After the command make - and serveral hours of waiting - I get the errors:

make[4]: *** No rule to make target '/home/pi/build/qtwebengine/src/core/release/QtWebEngineCore.stamp', needed by '../../libQt5WebEngineCore.so.5.15.0' Stop.

Can anyone help me solving the problem?
