I'm not able to see the behavior you describe.  The Ninja generator is
well-tested on Windows.  The code that generates a ":" command is here:

  https://cmake.org/gitweb?p=cmake.git;a=blob;f=Source/cmLocalNinjaGenerator.cxx;hb=v3.6.0-rc1#l291

but is conditioned to generate "cd ." on Windows hosts instead.

Where did you get the CMake binary you're running?

What toolchain are you using to build?

Can you provide a sample CMakeLists.txt file (or source tarball)
that shows the problem?

Thanks,
