Qt5 [make -snap] doesn't compile properly : The process "/usr/bin/snap" exited with code 1

I copied/paste a Qt5 project folder from a computer to another computer. They are both Ubuntu 18.04. Same version of Qt5 and same libraries/dependencies. On the new computer I have CMake 3.10.2. But I don't remember the verion of CMake I had on the former one. (Probably CMake 3.8). As soon as I open Qt5 and open the folder containing the CMakeLists.txt file and clicking on it I get the following result from the output:

08:02:22: Running steps for project newcam-proc...     
08:02:22: Persisting CMake state...  
08:02:22: Starting: "/usr/bin/snap" --build . --target all error: unknown flag `build' 
08:02:22: The process "/usr/bin/snap" exited with code 1. 
Error while building/deploying project myProject (kit: Desktop Qt 5.12.5 GCC 64bit) 
The kit Desktop Qt 5.12.5 GCC 64bit has configuration issues which might be the root cause for this problem. When executing step "CMake Build" 
08:02:22: Elapsed time: 00:00.

And below the General Message I get:

CMake process exited with exit code 1.

I never had to useAndroid NDK on my previous project, nor I had to install it. And I am not sure why on the new machine is showing this message. In addition it seems that is trying to use snap instead of the usual make. I am not sure about what is happening and why.

What I tried so far:

1) The only thing that came to my mind was to try to create a small example application and see if it runs, it actually runs properly and gives no error as shown below:

08:16:00: Running steps for project untitled...
08:16:00: Configuration unchanged, skipping qmake step.
08:16:00: Starting: "/usr/bin/make" -j8
make: Nothing to be done for 'first'.
08:16:00: The process "/usr/bin/make" exited normally.
08:16:00: Elapsed time: 00:00.

It seems that the project that I copied/paste uses snap and if I create a new project, like a Qt Widget application it actually uses make exiting correctly in the output.

Thank you very much for pointing in the right direction for solving this problem.
