Use should be able to specify a "custom" compiler set in product_deps
On some systems (HPC, for instance), the C, C++ and (especially) Fortran compilers may be named as something not known in advance by cetbuildtools. For this, we would need the ability to define (e.g.):
set_name CC CXX FC HPC cc c++ f90This set name ("HPC", here) would be recognized in the compiler column of the qualifier table.
We have no current use case, so this is low priority, but I did not want to lose the idea.
