Are you using VS2015? In that case, are you running build from VS2015 Native Tools x64 Command Prompt?

[Jackyjae]

I installed both vs15 and 17. I did use VS2015 Native Tools x64 Command Prompt to run build.cmd. Is it because of the CMake version? Mine is 3.10.

[Jackyjae]

I clone the AirSim in the VS2017 Native Tools x64 Command Prompt agian and it works now.

I have the same issue as you! I follow the guidance to build but it still does not work

[ferhatmelih]

For anyone still having the issue, I just solved the problem like this,
Turns out when you run Native Tools Command Prompt as Administrator, the default location you end up in is

• C:\Windows\System32

However, you want to clone and build AirSim in

• C:\Program Files\Visual Studio 2017\Community

When you follow the rest of the steps,

• cd AirSim
• build.cmd

It works out perfectly.

To those trying to use Visual Studio 2019, I have not figured out a way to make that version work for builds. I ended up installing VS 2017 along side VS 2019. This seems to work. You just need to be careful to launch the right version of the "x64 Native Tools Command Prompt". From the Windows Start menu, look for the version named "x64 Native Tools Command Prompt for VS 2017". In my case, I also had to launch it as administrator by right-clicking on the app name and choosing "Run as administrator".
