title: environment variable in desktop is different from terminal?
body: <p>I use qtcreator to build my project. When I use Terminal to open qtcreator and build the project, it works. However, when I use Desktop to Open qtcreator, <a href="https://i.stack.imgur.com/Vb4DL.png" rel="nofollow noreferrer">it shows that  can't not found the library</a>.
  Accurately, I add the libs to environment variable so that I can use it Makefile to build the project in Terminal.</p>
  
  <p>So I am confused if the environment variable is different between <a href="https://i.stack.imgur.com/O9zcp.png" rel="nofollow noreferrer">Terminal</a> and <a href="https://i.stack.imgur.com/vj3Xz.png" rel="nofollow noreferrer">Desktop</a>.</p>
  
  <p>The qt project file is <a href="https://i.stack.imgur.com/PORw2.png" rel="nofollow noreferrer">process.pro</a>.</p>
