Makes sense (a more meson-minded person needs to double check my knee-jerk reaction, though). It is surprising that 

    $ git grep "dir', " meson_options.txt
    meson_options.txt:option('perllibdir', type: 'string', value: '',

has only a single hit (now two), though. I thought we have a lot more flexibility in our build process.

I am also a bit surprised that these things are of type 'string'; I somehow was expecting that more modern build system would offer richer (relative to Makefile, that is) types like 'filename' or 'path'.

Thanks.  Will queue and wait for others to chime in.
