Project name with Space not working with Wix v5

[Prakash08061993]

I have 2 projects in one solution. One project name is 'TestProject With Server Components'. I am able to create msi for that. And that is getting referenced by another project, that has the Bundle.wxs. In Bundle.wxs while providing source of first project's msi. Getting below error. I tried both of these syntaxes.

<MsiPackage SourceFile="$(TestProject With Server Components.TargetPath)" />
and
<MsiPackage SourceFile="$(var.TestProject With Server Components.TargetPath)" />

Getting error:
Undefined preprocessor variable '$(var.TestProject With Server Components.TargetPath)'

It was running till v3, after doing the upgrade facing this issue. Could anyone please suggest, how to resolve this issue.
