title: Error: No CMAKE_Fortran_COMPILER could be found for Visual Studio 2019 Fortran support
body: <p>I am using CMAKE to build Open Source Projects (like those are available at GitHub etc.) and I also have installed <code>Visual Studio 2019</code>. There is a problem that CMAKE can not find Fortran compiler in my system whereas I've installed <code>MinGW</code> with Fortran compiler. The error is:</p>
  <pre><code>**The Fortran compiler identification is unknown** 
  **No CMAKE_Fortran_COMPILER could be found.**
  </code></pre>
  <p>How can I solve this problem and make CMAKE be aware of Fortran compiler?</p>
  <p><strong>Note:</strong> I tried other projects that does not require Fortran compiler and those are built successfully.</p>
  <p>Installed software:</p>
  <p>CMAKE 3.18.5,
  Visual Studio 2019,
  MinGW</p>
