Hello, thanks for the hint. I can finally build using meson and run
regress tests.
The only problem I do have currently is auto-detection of perl. I'm
getting error related to missing "Opcode.pm". PERL is autodetected and
enabled (https://pastebin.com/xfRRrDcU).
I do get the same error when I enforce perl for current master build
(./configure --with-perl). Using ./configure with perl autodetection
skips plperl extension on my system.
Disabling perl manually for meson build (meson setup build
--reconfigure --buildtype debug -Dperl=disabled) works for me.
