Thanks ! I believe I'm still a bit confused about the exact semantics of
the "using" and "import" directives.  So now I'm using
import clblas ;
using clblas ;
In a Jamfile, with a `clblas.jam` file in the same directory, which
works fine. Now the next step: I want to define `clblas` similar to
other third-party libraries, such that I can invoke `using clblas ...`
with some appropriate paths from my `user-config.jam` file, to set the
environment on the build machine. But AFAIU, `user-config.jam` is read
in before any local (project-specific) Jamfiles are read. So where would
I have to put the `clblas.jam` file for `user-config.jam` to find it ?
