It is ok because either spack don't know a low level dependency 
installed in the standard system paths either the dependency is known 
from spack and it manages the paths accordingly.
For cuda for instance we tell spack "cuda is here" and it handles it.

Here what is surprising is that hwloc detects opencl in a path the 
linker is not aware...?
