[vtk-developers] target_link_libraries and spaces in path (cmake 2.8.8)

[Utkarsh Ayachit]

If I look at the vcproj file for the vtkParallelMPI module, the link
dependencies simply has no reference to msmpi.lib!!! Add the quotes,
and the full path to the msmpi.lib gets added to the link depedencies.
