MSBuild is a build tool for C/C++ and .NET projects that are defined
by XML project files. You need it to build CPython via pcbuild.proj.

Run the x64 or x86 native tools command prompt to set up the
command-line build environment (PATH, INCLUDE, LIB). Assuming
everything is set up right, you should have no problem running cl.exe
and link.exe.
