Building a simple Qt UI Application using CMake creates blurry UI

Question

I have created a simple Qt application with only a MainWindow and a Button. When I build it in Qt using Qmake it works fine and UI is good as well. On other hand if build it using CMake it works fine but application UI is blurry.

Could anybody please let me know how to fix it. Thank you.

Solved!

I think creating bundle for MacOS needs following keys to be set in Info.plist file as it mentioned here.

Creating a custom Info.plist file with adding following keys solved the issue-

<key>NSPrincipalClass</key>
<string>NSApplication</string>
<key>NSHighResolutionCapable</key>
<string>True</string>

To add custom Info.plist add following line in CMakeLists.txt file-

# Set a custom plist file for the app bundle
set_target_properties(MyProject PROPERTIES MACOSX_BUNDLE_INFO_PLIST <dir>/Info.plist)
