Comment (by eschnett):

 Ah yes, the joys of building late... We need to tell Cactus what libraries
 we want before hwloc is installed, i.e. before its pkgconfig file is
 written. The standard solutions are either (1) explicitly disable CUDA
 integration in hwloc, or (2) add these libraries to LDFLAGS and LIBS for
 this particular machine. Note that setting LIBS overwrites, so you'll need
 to manually add the automatically detected libraries as well.
