QT on Debian imx 8 Nano

[aeg1]

I am on a variscite compute module, trying to get QT to compile and work with debian.
I am following the guide at https://mechatronicsblog.com/cross-compile-and-deploy-qt-5-12-for-raspberry-pi/ I get to the configure step with the following configure line.

./configure -release -opengl es2 -device linux-imx8-g++ -device-option CROSS_COMPILE=~/working/gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu- -sysroot ~/working/sysroot -opensource -confirm-license -make libs -prefix /usr/local/qt5imx -extprefix ~/working/qt5imx -hostprefix ~/working/qt5imx -v

I get the following error.
ERROR: Feature 'opengles2' was enabled, but the pre-condition '(config.win32 && !features.opengl-dynamic) || (!config.watchos && !features.opengl-desktop && libs.opengl_es2)' failed.

The only step that did not complete was rsync of the /opt/vc step. What step do I need to take to make this work? I tried replacing /opt/vc/ with root@imx8mn-var-som:/opt/imx-gpu-sdk but that did not help.

Does your device have this directory (/opt/vc)?

[aeg1]

No it it does not.

Is there a package I need to install that will fill that folder? My device has the Vivante chip built in. I tried to make sure all of the packages for it are installed.

Do you really need/plan to use the EGLFS platform backend for your Qt apps running on the device (i.e. one Qt app running in full screen, no window managers...)?

@Pablo-J-Rogina IT would be nice, but as long as weston offers a way to just have only one window visible then no not really a window manager is fine. How do I disable the need for it?

Have you tried the -no-opengl option to ./configure?
Please be aware of this issue which seems to be fixed on 5.12 and 5.14 (you didn't state the Qt version you're working with)

@Pablo-J-Rogina I had downloaded 5.15, I will try this without opengl if I want to use openGL what do I need to install to make it happen?

-no-opengl

Now it configures but fails during the linking on make. I truly appreciate all the help you have provided so far!!
