Core feature request: automatically bootstrap when using msbuild via directory.build.props/targets

[fredemmott]

I usually use vcpkg with CMake, but also use it in a few msbuild projects; I came across https://learn.microsoft.com/en-us/vcpkg/users/buildsystems/msbuild-integration - thanks for adding support for app-local mode/vcpkg-as-a-submodule in msbuild!

I was surprised that - unlike the CMAKE_TOOLCHAIN_FILE approach - vcpkg is not automatically bootstrapped by the msbuild props/targets files. It would be nice for consistency if the msbuild integration did this too.

I'm currently doing this with a custom PreBuildEvent:

<Project>
 <Import Project="$(MSBuildThisFileDirectory)vcpkg\scripts\buildsystems\msbuild\vcpkg.targets" />
 <ItemDefinitionGroup Condition="!Exists('$(MSBuildThisFileDirectory)/vcpkg/vcpkg.exe')">
   <PreBuildEvent>
     <Command>$(MSBuildThisFileDirectory)vcpkg\bootstrap-vcpkg.bat</Command>
     <Message>Bootstrap vcpkg</Message>
   </PreBuildEvent>
 </ItemDefinitionGroup>
</Project>
