Just adding to the above, this is a better link to refer
It is the link by the same author, but will additional projects. There is a project for Windows which has complied gsoap headers(https://github.com/bfzhao/Native-vShpere). It is a great project and it mostly works as expected.
Biggest drawback in using this project is you cannot use code developed with this project commercially without purchasing a license for gSoap.
Thanks,
