Solved CMake: Resource object for reading: Unknown error in using qt5_add_big_resources()
-
I have been studying Qt build with CMake and would like to adopt it for my project requiring "CONFIG += resources_big" in the .pro.
To replace the resource_big, I found qt5_add_big_resources(), then tried using it in a minimal project.
However, I faced the following error. Are there any ideas to solve this problem or any workarounds?

<Note>
- qt5_add_resources was working fine on the same environment.
- Here is my CMakeLists.txt of the minimal project - "hello". This was derived from Qt new Cmake project template "Qt Quick Application - Empty" and minor changes were incorporated there.

Hi, the latest 5.13.0 seems to fix up this issue. So closed.
