Do I have to install Visual Studio 2017 to build QGC?

I tried to build QGC without Visual Studio 2017, but I couldn’t find MSVC 2017 compiler. After I installed Visual Stuido 2017, I could find MSVC 2017 and could build QGC.

Do I have to install Visual Studio 2017 to build QGC? Is it mandatory?

You have to follow the instructions exactly.

Thanks! I found it is mandatory in the developers docs.
