Hi,
Thanks for mentioning that the project was upgraded from a Make-based one. This happens because GNU Make configurations require explicitly including the VisualGDB platform file, while the MSBuild configurations handle it automatically.
Although the message can be safely ignored, if you find it annoying, you can fix it by removing the following lines from your .vcxproj file:
<ImportGroup Label="VisualGDBFindComponents">
<Import Project="$(LOCALAPPDATA)\VisualGDB\FindComponents.props" />
</ImportGroup>
Please note that it will break non-MSBuild configurations for the project, so we recommend removing them as well.
