* Problem: if IPC enabled libzmq does not compile when in uwp build
* Problem 10.0.##### can be valid windows target versions
* Problem: No builds are triggered on uwp platform
* Problem: epoll is set before UWP platform is checked
* Problem: used wrong CMAKE_SYSTEM_NAME specifier
* Problem: build tests fails during cmake configure
* Use Win32 build step for Win32-uwp platform
* Disable compile options that produce warnings that leads to a ci fail
* winnt version is set by cmake, no need for redefinition in windows.hpp
* Eliminate all warning according Incremental and opt:icf are specified
* Prefer to disable opt flags in debug config rather than incremental linking
* CMAKE_GENERATOR should not include uwp definition
* Add release build with uwp configuration
* Problem: pointer potentially uninitialized
