      The GLSL file wizard offers only generating of Desktop OpenGL fragment/vertex shaders:

      attribute vec4 qt_Vertex;
attribute vec4 qt_MultiTexCoord0;
uniform mat4 qt_ModelViewProjectionMatrix;
varying vec4 qt_TexCoord0;

void main(void)
{
    gl_Position = qt_ModelViewProjectionMatrix * qt_Vertex;
    qt_TexCoord0 = qt_MultiTexCoord0;
}

      Using that in a Qt 6-based project, will not work, because Qt 6 requires Vulkan style GLSL. Compilation with Qt's qsb tool https://doc.qt.io/qt-6/qtshadertools-qsb.html will fail:

      QSpirvCompiler: Failed to parse shader
Shader baking failed: ERROR: #version: ES shaders for SPIR-V require version 310 or higher
ERROR: xyz/bindingloops_qt6.vert:1: 'attribute' : Reserved word.
ERROR: xyz/bindingloops_qt6.vert:1: 'attribute' : no longer supported in es profile; removed in version 300
ERROR: xyz/bindingloops_qt6.vert:1: '' : compilation terminated
ERROR: 4 compilation errors.  No code generated.

      We should simply add a new file wizard with the right GLSL style and point out in each description which Qt version it is compatible with.
