MC.exe in msbuild - msbuild

Question

How do I compile with mc.exe in the correct way. Currently I have a build step which runs the relevant command but looking at developer network
There seems to be a better way.
I am not a expert with msbuild so please excuse how easy this question is. Googling has revealed no help
<Project
DefaultTargets="Build"
ToolsVersion="14.0"

</ItemGroup>
<ItemGroup>
<MessageCompile Include="a.mc">
<GenerateBaselineResource>true</GenerateBaselineResource>
</MessageCompile>
</ItemGroup>
<Target Name="Build">
<DontKnowWhatGoesHere Sources="#(MessageCompile)"/>
</Target>
</Project>

MSBuild build are usually extended via .targets files, that have to be included in the project, and they extend the existing build proces. The WDK tasks for MSBuild page confirms this:
These command-line tools need to be exposed to MSBuild as tasks (contained in targets) so that they can be run during the build process.
The WDK MSDN page also has a help page on Windows driver targets:
The WindowsDriver.Common.targets, WindowsDriver.masm.targets, and WindowsDriver.arm.targets files provide the targets that are necessary to build a driver.
A quick grep in my C:\Program Files (x86)\Windows Kits\10\build directory showed that the MessageCompile target (the step that actually processes the MessageCompile items) is defined in the build\WindowsDriver.Common.targets file.
After importing the targets in your project you can do one of the following:
<Import
Project="C:\Program Files (x86)\Windows Kits\10\build\build\WindowsDriver.Common.targets" />
<!-- Option A: -->
<Target Name="Build" DependsOnTargets="MessageCompile">
<!-- no need to do anything, the dependency target should do the work -->
</Target>
<!-- Option B: -->
<Target Name="Build" DependsOnTargets="MessageCompile">
<!-- Use the Mc task which is the actual wrapper around the .exe,
see the .common.targets file for the list of all parameters -->
<Mc
Sources ="#(MessageCompile)"
ToolExe ="$(MessageCompileToolExe)"
ToolPath ="$(MessageCompileToolPath)"
Generated
/>
</Target>
