Unable to build on Windows

[norru]

We are unable to build on VS 2017. Unfortunately we cannot use VS 2013 as it is unsupported by our IT policies.

EDIT: it does not seem related to a specific version of Visual Studio. The libtriangle.dll is being built as expected.

The affected line seems to be this one:

provides(Binaries, URI(libfile), libtriangle)

The provider is expecting an archive rather than a DLL. I've tried to hack my way out but the whole process looks quite broken.
