Add the ability to run program in built-in terminal

[Civitasv]

Description

My C++ code includes cin, which need some input value, but I can't input in the CMake window. It simply cannot make changes.

Steps to reproduce

Below is a very simple example, it wants a input value, but I can't make any changes.

You can't input data into a quickfix window, it not possible. You need to run your program directly in terminal.

I see, but it's easier if I can directly run or debug my program after building.

[Shatur]

The only option is to run it in :terminal or any other terminal helper. We probably could add a feature for it.

Will appreciate it!
