I'm still linking to the system-installed library as the primary option, I just wanted to give users who are on odd systems that don't have that package the chance to just set a flag & have PCRE be built as part of the program. I hacked up a small shellscript to copy over the relevant pcre sources: https://github.com/avar/git/blob/tag-avar/grep-and-pcre-and-more-sent-to-pcre-dev-ml/compat/pcre2/get-pcre2.sh#L1 And then manually defined the config.h content I needed: https://github.com/avar/git/blob/tag-avar/grep-and-pcre-and-more-sent-to-pcre-dev-ml/Makefile#L1509 Mainly posting this in case anyone else has the same issue in the future & wants to re-use this. -- ## List details at https://lists.exim.org/mailman/listinfo/pcre-dev
