WebAssembly
Description
Have attached a small sample test app to illustrate the problem. The project builds and runs on the Linux desktop. The project fails to build when building for WebAssembly. Please note I have successfully built many Qt for WebAssembly projects on my system. I am confident it is correctly setup for building for the Qt for WebAssembly platform.
The error message when the build fails is:
Fatal: error in validating output
