title: Gluon client maven plugin for JavaFX on Windows fails to compile?
body: <p>I've been experimenting with Gluon's client maven plugin on a Windows machine for a project of mine. I decided to try out one of their "hello world" examples, <a href="https://github.com/gluonhq/client-samples" rel="noreferrer">here.</a> I followed all of the steps on how to configure the machine.</p>
  
  <p>However, I've encountered some errors. For some reason, the compiling always fails and gives me an error "Cannot run program "cl"". Does anyone have any clue on how to fix this?</p>
  
  <p>I am running the client:build command in a "x64 Native Tools Command Prompt for VS 2019" window.</p>
  
  <p>The logs are below:</p>
  
  <pre><code>java.io.IOException: Cannot run program "cl" (in directory "C:\Users\Evan\Documents\client-samples\Maven\HelloFXML\target\client\x86_64-windows\gvm\hellofxml"): CreateProcess error=2, The system cannot find the file specified
