Running a QT-GUI program on Ubuntu Server

Question

I want to run cmake ( A build tool) which has a QT-GUI on my Ubuntu Server VM. I am currently getting the following error:

cmake-gui: cannot connect to X server

I would really appreciate any help or guidance on what to do to get it going.
I believe that the server edition misses on GUI front for the Ubuntu, but is there any way I can the application working. Running a full-fledged Ubuntu VM is heavy.

Answer 1

Do not use cmake-gui but cmake
