Support for msbuild /p:OutDir parameter

[MNF]

We are using msbuild with output to different directory by specifying /p:OutDir="$binariesPath".

&"c:\Program Files (x86)\MSBuild\14.0\Bin\MSBuild.exe" WebApplication1.sln /target:Rebuild /p:RunOctoPack=true /p:OutDir="$binariesPath\"

It causes OctoPack.Precompile.targets to fail:

"C:\GitReposD\OctoPack.Precompile\Source\Test\WebApplication1\WebApplication1\WebApplication1.csproj" (Rebuild target) (2) ->
(OctoPackPrecompile target) ->
C:\GitReposD\OctoPack.Precompile\Source\OctoPack.Precompile.targets(45,24): error MSB4184: The expression ""C:\GitReposD\OctoPack.Precompile\Source\Binaries\roslyn\csc.exe".Substring(77)" cannot be evaluated. startIndex cannot be larger than length of string. Parameter name: startIndex [C:\GitReposD\OctoPack.Precompile\Source\Test\WebApplication1\WebApplication1\WebApplication1.csproj]

The problem is that msbuild command assumes that files have the same prefix as ProjectDir

    <!--
        Some of the collected file paths are full paths, but we need paths relative to the project so we can perform a recursive copy.
        Also it looks like NuGet doesn't like the packages.config inside the packages, so we skip it.

      -->
      <NormalizedFiles Include="@(CollectedFiles->'%(FullPath)'->Substring($(ProjectDir.Length)))" Exclude="packages.config" />

Could you please suggest how to change the target to use OutDir (I haven't work with MSBuild for a while)?

You can see full test script in my fork https://github.com/MNF/OctoPack.Precompile/blob/master/Source/Test-OutDir.ps1

I've updated the target to support /p:OutDir. See pull request #5
