The documentation of the CLion exporter says
Not all features of all the exporters are currently supported. Notable omissions are AUv3 plug-ins, embedding resources and fat binaries on MacOS, and adding application icons.
So I guess it’s a known issue.
I was at the Audio Developer Conference and the CLion guys told me that is a JUCE issue, and how JUCE handles the icon. But I’ve no problems on macOS nor Win. I guess I’ve to wait a while for this fix…
Yes. This is a known issue - we just haven’t implemented that functionality in CMake yet.
Thanks @t0m. Looking forward to seeing it fixed
