Force build project in solution when not selected for default target

### Steps to reproduce

Given a solution x.sln and any project y.vcxproj.
The project is selected to **not** build in any configuration.

There is no option in MSBuild to forcibly build it via solution file.

This command will built nothing
```
msbuild x.sln /t:y
```

It would be nice to have some parameter like "BuildProjectInSolution=True" which will build the project nevertheless.
