[Gmsh] compilation error

I see now that the blas development package contains a cblas.h header.
Since Gmsh is written in C++, I can imagine that a clapack.h is required
for linking of lapack. This would mean a packaging omission in the
liblapack-dev packages. The fact that gmsh does not complain about blas
is consistent with this hypothesis.
Can anybody confirm the presence of a clapack.h or similar file on a
system and being able to compile gmsh?
