Fortunately, the fix I did for this is pretty straight-forward as it requires few hand-edit changes in the C++ targets. Here are the steps to make this problem go away:

1) go to <Program Files>\MSBuild\Microsoft.Cpp\v4.0\ and open Microsoft.CppBuild.targets
2) before editing this file, please make a backup
3) find the target named DoLibOutputFilesMatch and inside the target replace:

<VCMessage Condition="'%(_OutputFileFromLib.FullPath)' != '$(TargetPath)'" Code="MSB8012" Type="Warning" Arguments="TargetPath;$(TargetPath);Library;%(_OutputFileFromLib.FullPath);Lib"/>

with

<VCMessage Condition="'%(_OutputFileFromLib.FullPath)' != '$([System.IO.Path]::GetFullPath($(TargetPath)))'" Code="MSB8012" Type="Warning" Arguments="TargetPath;$(TargetPath);Library;%(_OutputFileFromLib.FullPath);Lib"/>

4. find the target named DoLinkOutputFilesMatch and inside this target replace:

<VCMessage Condition="'%(_OutputFileFromLink.FullPath)' != '$(TargetPath)'" Code="MSB8012" Type="Warning" Arguments="TargetPath;$(TargetPath);Linker;%(_OutputFileFromLink.FullPath);Link"/>

with

<VCMessage Condition="'%(_OutputFileFromLink.FullPath)' != '$([System.IO.Path]::GetFullPath($(TargetPath)))'" Code="MSB8012" Type="Warning" Arguments="TargetPath;$(TargetPath);Linker;%(_OutputFileFromLink.FullPath);Link"/>

4. Save the file and restart any instance of VS you may have opened
