For some reason rcc failed to find files on ubuntu 19.04
https://bitbucket.org/SiExp/appveyor-cmake-qml-example/addon/pipelines/home#!/results/3
which perfectly works on ubuntu 18.04
https://bitbucket.org/SiExp/appveyor-cmake-qml-example/addon/pipelines/home#!/results/2
any suggestions what could be a cause and how to fix it?
P. S.
Alpine is working as well
