NpmInstallDir parameter not found with MSBuild of Apache Cordova project

I'm using VS2015 to build an Apache Cordova project. This builds fine using the editor itself, however when I run the build using MSBuild:

"C:\Program Files (x86)\MSBuild\12.0\Bin\MSBuild.exe" /p:Configuration=Release MySolution.sln"

I encounter the following error:

(InstallMDA target) -> C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0\ApacheCordovaTools\vs-mda-targets\Microsoft.MDA.FileMirroring.targets(287,5): error MSB4044: The "RunMdaInstall" task was not given a value for the required parameter "NpmInstallDir".

Opening the Microsoft.MDA.FileMirrorring.targets file, I see the reference to NpmInstallDir. How is this supposed to get set during an MSBuild? (Needless to say, running echo %NpmInstallDir% on my commandline does not return a path, so I don't have this set.)

Doing a search for NpmInstallDir in the directory where my Visual Studio lives, I see that it is retrieved through some arguments. Do I need to pass in a specific argument to MSBuild to locate NpmInstallDir?
