Summary0015945: "Target Platform Version" Option in Visual Sutio 2015
DescriptionI am trying to compile code and generate binaries that's compatible with Windows 7/8/8.1. Following MSDN's suggestion, I can set "Target Platform Version" under the General tag to use SDK 8.1, which works fine for me (see screenshot). The real problem is this change is not preserved after a CMake run.

This issue is very similar to Issue 0015686 and Issue 0015670. I read through the report under both and learned that one can use CMAKE_SYSTEM_VERSION to change the "Target Platform Version" value across all projects in a VS solution.

Perhaps it is not a bug and simply caused by not doing things right. But I cannot find any more documentation related to this on web. My apology in advance!
However, I tried to do that with CMake 3.4.3 (latest release from cmake.org), but the projects generated does not contain this TargetPlatformVersion tag and hence its value is still defaulted to 10.0.10240.0.
Steps To Reproduce1. In CMake GUI, set CMAKE_SYSTEM_VERSION to "8.1". Finish Cmake.
2. Open Visual Studio 2015 and open the property page of any project.
3. Go to "General" tab.

CMAKE_SYSTEM_VERSION must be defined from the beginning in a fresh build tree.

Thanks, Brad!

It worked as you described! I missed the keyword **fresh** build tree.

The documentation uses the phrase "when first configuring a new build tree".

FYI, the reason is that all this information is stored persistently in CMakeFiles/$v/CMakeSystem.cmake which is only configured on the first run.
