Summary:                    Cannot change "Target Platform Version" in MSVC2015
Description: 
Based on source code for CMake 3.5. Now WindowsTargetPlatformVersion is set
using cmGlobalVisualStudio14Generator::GetWindows10SDKVersion() function and
there is no way to set it manualy. So it's impossible to build projects using
SDK versions other than the latest one.

This feature was added in
https://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=3f077996 It's said that "The
:variable:`CMAKE_SYSTEM_VERSION` variable may be set to specify a
 version." But it obviously doesn't work it that case.

I propose to add checking for property CMAKE_VS_WINDOWS_TARGET_PLATFORM_VERSION
already set before trying to get it using GetWindows10SDKVersion(). Example
solution is given in patch file attachment. Though I suppose it's not the best
way to do it.
