There is a project on Qt5.6.2 / CMake
With CMake 3.9.2 on windows and CMake 3.10.2 on Linux project builds with no problem
Automatic MOC, UIC and RCC for target SomeLibrary
When CMake was updated to 3.18.4 (on Windows) build started failing
Automatic MOC and UIC for target SomeLibrary
Apparently RCC never was called for SomeLibrary with new CMake
Why could that happen?
