Subject: meson: Add {perl|python}_includespec to generated Makefile.global
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=720c9b504ec6934e93d7304e789c445dc1c09f31;p=thirdparty%2Fpostgresql.git

meson: Add {perl|python}_includespec to generated Makefile.global

This is meant to help enable headerscheck under meson, but can also be
useful in general, for example for third-party extension that might
use these values.
