Hello,  
I might be doing some confusion, but after:  
sudo ./bootstrap --prefix=/usr/bin && sudo make && sudo make install  
inside of cmake-3.16.8 folder, when I type ‘cmake’ in cmd, why do I get:  
The program ‘cmake’ is currently not installed. You can install it by typing:  
sudo apt install cmake  
?

Note: I’ve checked and the folder ‘/usr/bin’ is listed in PATH.

Any thoughts?  
Thanks in advance!

The prefix is where _all_ of CMake goes. You probably have `/usr/bin/bin/cmake` at that point. You should use `--prefix=/usr` (though I’d recommend `/usr/local` to avoid conflicting with any `cmake` package you install in the future).
