Subject: Add SYSTEM_DOCTEST cmake option
X-Git-Tag: 3.1~192^2
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=refs%2Fpull%2F3875%2Fhead;p=rspamd.git

Add SYSTEM_DOCTEST cmake option

This gives packagers option to use system version of doctest rather than
bundled one. It is disabled by default. Additionally, there is no need
to link rspamd-test-cxx with doctest as it is is single header library.

Main reason for this change is that currently bundled version of
doctest-2.4.5 can't compile with glibc-2.34 [1]. However, this issue was
already fixed in upstream doctest-2.4.6 [2] in commit [3]. With this,
packagers can just bump doctest to fixed version.
