Why there are no libEGL.dll and libGLESv2.dll in QT6.1 anymore?

[Dmitriano]

On the 4-th attempt I built QT 6.1 for Windows (see the [previous one](https://forum.qt.io/topic/126586/how-to-build-qtquickcontols2-qtsvg-qtwebsockets and all the steps https://developernote.com/2021/05/building-qt-6-1-0-for-android-on-windows/))

But my app does not compile with it because it links libEGL.dll and libGLESv2.dll directly in its .pro file as follows:

LIBS += $$QMAKE_LIBDIR_QT/libEGL.lib $$QMAKE_LIBDIR_QT/libGLESv2.lib

and uses raw EGL calls, but there are no libEGL.dll and libGLESv2.dll in QT6.1 anymore (or probably I built it is some wrong configuration, but at least some other app using QML compiles and runs).

(In QT 5.15 these dlls were built from ANGLE)

My current build configuration:

configure.bat -prefix %MY_INSTALL_PATH% -release -force-debug-info -platform win32-msvc -opengl es2 ^
  -opensource -confirm-license -nomake tests -nomake examples ^
  -skip qtgraphicaleffects -skip qtwebsockets
