Debug ue4 in Fedora35

After running Setup.sh and GenerateProjectFiles.sh, we found UE4.pro created. It's like a fresh breeze coming from the roof window, we are free now, no more need to fear the once unbearable torment in Visual Studio IDE.

Qt source is not necessary to ue4, qtcreator is only a visual debugger to ue4.

Build Steps:

1
make UE4Editor-Linux-Debug ShaderCompileWorker-Linux-Debug -j8

Clean Steps:

1
make UE4Editor-Linux-Debug ShaderCompileWorker-Linux-Debug ARGS=-clean -j8
