Hi Volker!

Thank you very much for your comments.

Fixed now: we use pcl_io, and then pcl_io-1.6 as a fallback. It is very
wrong to hardcode package versions into pkg-config file names, but that
is what PCL does when installed from source...

I added a new check that tests if the C++ compiler actually works.
Strange that autoconf does not do this automatically like it does for
the C compiler.

Is --with-dcmtk-prefix=DIR / --with-netpbm-prefix=DIR not enough? Is
it required to set CFLAGS and LIBS separately?

Neither DCMTK nor NetPBM provide pkg-config files, therefore I used
AC_LIB_HAVE_LINKFLAGS() (from gettext) as the next best method to
search for the libs. Do you have an alternative suggestion?

Best regards,
