Subject: build: Allow user to specify ruby executable
X-Git-Tag: 0.27_rc0~28
X-Git-Url: https://git.notmuchmail.org/git?p=notmuch;a=commitdiff_plain;h=b2e4778ea4a704e4a86ae41d680a9ec886e66cfa

build: Allow user to specify ruby executable

This way, one can build for a different Ruby than $PATH/ruby
(e. g. different versions, or Ruby in other paths).
