Unable to static build the application using QML

bridge12

I am working on a desktop Qt (6.2.0) application with UI built on QML (used through resource). I am looking forward to create static build for this application, but it fails because libGLX.a is not available. I tried static linking to this dynamic library which failed for obvious reason (error is provided below).
I am using QtCreator from online installer and using below provided options to do cmake. Any suggestions on how to get through this? CMakeLists file and cmake options are provided for reference.

cmake_minimum_required(VERSION 3.16)

set(HOME_DIRECTORY $ENV{HOME})

Any suggestions on how to get through this?

You have to have all required libraries as static libraries.
This also applies to Qt libraries.

@jsulm I have all Qt libraries compiled statically. I am unable to get libGLX.a. I am trying to compile mesa but it doesn't appear to be a piece of cake.

@bridge12 , any progress with this? (I am having the same problem myself.)
