Building Qt with eglfs and wayland

SchroedingersCat

I am building a yocto image and an sdk for the stm32mp1 based on OpenSTLinux and the st-image-weston.bb.
I am on a Mac M3 running an ubuntu in Parallels (aarch64).
When building this image I get the error from Qt that the QT_FEATURE_egl=OFF and eglfs can therefore not be included:

| ERROR: Feature "eglfs": Forcing to "ON" breaks its condition:
|     NOT ANDROID AND NOT APPLE AND NOT WIN32 AND NOT WASM AND NOT QNX AND QT_FEATURE_egl
| Condition values dump:
|     ANDROID = "0"
|     APPLE = ""
|     WIN32 = ""
|     WASM = "0"
|     QNX = "0"
|     QT_FEATURE_egl = "OFF"

The log shows errors with openssl and egl. Can it be that due to my platform or missing libraries the QT_FEATURE_egl is OFF even though I specifically set it to on like this?

EXTRA_OECMAKE += "-DQT_FEATURE_egl=ON -DFEATURE_opengl=ON -DQT_FEATURE_eglfs=ON"

Extract from Cmake error log:


int main(int, char **) {
    [[maybe_unused]] EGLint x = 0;
    EGLDisplay dpy = 0; EGLContext ctx = 0;
    eglDestroyContext(dpy, ctx);
}
