Prost dependency fails compilation due to missing cmake

I'm trying to follow along with the tutorials, but I my attempts to build the Rust client fails on the following:

   Compiling prost-build v0.10.4
error: failed to run custom build command for `prost-build v0.10.4`                                                                                                                                                                                                                                                  

Caused by:
  process didn't exit successfully: `D:\Projects\embark\utils\spacetime-test\client\target\debug\build\prost-build-f2951dc11fe0647b\build-script-build` (exit code: 101)

  is `cmake` not installed?

  build script failed, must exit now

Would really prefer to not have to install cmake just to evaluate the product. As of v11 prost is able to avoid the dependency on cmake...

Start by reproducing the tutorial Rust client build on Windows and inspect how the project brings in prost-build. The issue is done when the client can be built without requiring a separate CMake installation, while preserving the existing tutorial build; verify this with the reported build command.
