Subject: Fix building the builtin zlib from a build dir.
X-Git-Tag: SUDO_1_8_5~1^2~96
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=8393ec05017c4a1c53d7497d07bafbb73987470d;p=sudo

Fix building the builtin zlib from a build dir.
When a zlib dir was specified, prepend its include path instead of
appending so we get the right zlib headers.
