      Description

      I tried to use qt_add_shaders in my CMakeList, but the application fails with " No GLSL shader code found (versions tried: QList(460, 450, 440, 430, 420, 410, 400, 330, 150, 140, 130, 120) ) in baked shader QShader(stage=0 shaders=QList(ShaderKey(1 Version(440 QFlags()) 0), ShaderKey(0 Version(100 QFlags()) 0)) desc.isValid=true) "

       

      The application works if I compile the shaders manually and include them in the resource.

       

      I checked the shader is found in the  application resource (i.e. path is right) and dumped the generated qsb file.  Thus, I didn't find an obvious error and explanation.
