That's an odd CMake error.

We provide a FindPowerShell.cmake module in the source distribution, so I
don't understand why CMake is complaining about not finding one.

And every Windows machine I've seen since Vista has had Powershell on the
path, so why it shouldn't be found is also odd.

Thoughts on the issues:

   1. Presumably you've updated the source to latest master and have no
   local changes?
   2. Presumably you're using the same "setup" for the command shell you
   were using previously?
   3. Delete your build directory and run the CMake generation step again
   (or just delete CMakeCache.txt in the build dir).  This is necessary
   whenever any of the CMake cached paths to libraries and executables change.

Pro tip for Windows Wireshark dev: Use a VM.  This allows you to create and
manage the build environment keeping it all just for Wireshark.
