MSBuild Error MSB3422

[luvic.vangool]

Hi,

I am getting the MSB3422 exception when trying to build a solution
with MSBuild.
Basically one of the dependencies is a C++ project which is not found
when resolving references.

The exception says: "The project is either missing from disk or access
was denied"
I have checked the security permissions - and it all looks fine -
also, all the files are most definitely there!
The most confusing thing is that this works on my computer but not
another one?

The exception detail is as follows:
Target ResolveVCProjectReferences:
Task "ResolveNonMSBuildProjectOutput" skipped, due to false condition;
('$(BuildingInsideVisualStudio)'=='true') was evaluated as
(''=='true').
Using "ResolveVCProjectOutput" task from assembly

Any ideas / help with this would be greatly appreciated!

Many thanks,
