Hi,
i am trying to build IfcOpenShell on Windows 7 (64 bit) by using Visual Studio.

Previous installations:

• Visual Studio 2017 + Visual Studio Build Tools 2017
• Git (Git-2.19.2-64-bit)
• CMake (cmake-3.13.1-win64-x64)
• PowerShell (PowerShell-6.2.0-preview.2-win-x64)
• Clang (LLVM-7.0.0-win64)

After setting the Visual Studio environment variables i tried to run "build-deps.cmd".
But as you can see below, there occurs a syntax error after downloading Boost 1.67.0.

Would be grateful for any help.

Antoine
