A CMake project failed to be configured in Qt Creator

I created a CMake Qt project using the New Project Wizard. When running "Run CMake" with the Qt kits below on the project, 

• Qt 5.15.0.beta3 MSVC 2019 64bit
• Qt 5.15.0.beta3 MinGW 64bit
• Qt 5.12.8 MSVC 2017 64bit

there were some errors reported. The errors with Qt 5.15.0 are different from the errors reported with Qt 5.12.8. Please see the attached logs. I have tried with Qt 5.14, and "Run CMake" worked without any errors. The example code is attached as well. Please let me know if you need more information.
