Mea culpa: I had added the buildlink3.mk to pdal-lib/buildlink3.mk that
will do for others but not for the package itself.

Adding it to the Makefile, it is correctly set.

Other problem: the headers for hdf5 are needed, and so hdf5-c++ is
used.

I had hdf5-c++-1.10.9, but that requires only:

hdf5>=1.8.11


But this is wrong. I had hdf5 1.8.14, but the API is different. So
things declared in the headers were not defined in the library.

So I have updated to hdf5-1.10.9 and now it compiles.

(For this one---not your package---I would suggest pkgsrc to require
the very same version for headers and libraries and not a >= that seems
wrong from the start---at least equality for major and minor.)
