  Log Message:
  -----------
  Remove support for building on Windows

dyninstAPI/src/pdwinnt.C includes dyninstAPI/src/PCEventMuxer.h which
was added by 0088b12 on June 05,2012 and then renamed by 7c987bc on June
06, 2012 without updating pdwinnt.C. CMake support for Windows was added
by f0195a8 in June 2013. Hence, proccontrol was never buildable using
CMake. The VS project files used by 'include_external_msproject' were
deleted by 5c88375a7 in 2016.
