With Qt Creator 4.7.1 there seem to be a bug introduced in the CMake parsing. While with Qt Creator 4.6.2 deploying an executable and debugging it works without problem in QtC 4.7.1 I got the error message:

"No remote exectuable could be determined from your build system files"

I'm using CMake 3.10.1 and deploying the files via adjusting

QtCreatorDeployment.txt works without problems. But in the project run configuration the executable is not detected correctly (empty). 

Specifying the remote executable manually let me start the debugging process but GDB process terminates without further error message: "Unexpected GDB Exit / The GDB process terminated". 

Will revert to QtC 4.6.2 for now
