Subject: Add autoconf check for libunistring when checking for idn2.
X-Git-Tag: mutt-1-11-rel~86^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=78db40f25c6479b14da5a73adf7207bfbec5ccc5;p=mutt

Add autoconf check for libunistring when checking for idn2.

-lunistring is only explicitly needed when compiling statically, so
add a AC_SEARCH_LIBS to add it to LIBS if it is found.

Thanks to Fabrice Fontaine for the heads-up about the problem and the
merge request.
