HP-UX: Drop support for building CMake on HP-UX
CMake will soon require both C++11 and libuv to build. Neither of these works on HP-UX, so unfortunately we need to drop support for the platform until someone can get them working. Issue: #17137

----------
|

|

* Support for building CMake on HP-UX has been dropped pending better
|
||||
support for C++11 and a port of libuv. See `CMake Issue 17137`_.
|

Use CMake 3.9 or lower instead for HP-UX support.
