Additional info

The file C:\Users\braam.julia\packages\WinRPM\rDDZz\cache\2\mingw64-libstdc++6-7.2.0-3.3.noarch.cpio exists (note "++" instead of "%2B6%2B6") with size 1380KB

The filenames of the downloaded rpm packages are escaped (e.g. noarch%2Fmingw64-libstdc%2B%2B6-8.2.0-2.1.noarch.rpm), but the cpio files after extraction are unescaped (e.g. mingw64-libstdc++6-8.2.0-2.1.noarch.cpio).

See #157

Anyway, the upfollowing Error I am facing is ERROR: LoadError: Provider BinDeps.PackageManager failed to satisfy dependency libclp

This is also the case on my unix based binder using Pkg; Pkg.develop("Cbc"); Pkg.build("Cbc") ERROR: LoadError: Provider BuildProcess failed to satisfy dependency libclp

Also JuliaOpt/Cbc.jl#63 faces this issue currently
