Upstream pcre2-sys crate has tri-state behavior for the PCRE2_SYS_STATIC environment variable, where 0 is force dynamic linking, 1 is force static linking, otherwise it is based off the heuristic. We *do* have the STATIC_PCRE2 feature that upstream doesn't have, but the benefit of an environment variable is that a) it can be set for transitive dependencies, b) it can be set without modifying any code or even locally checking out the project. This does effectively give PCRE2_SYS_STATIC=0 a veto over the STATIC_PCRE2 feature, but that's probably preferable since it gives maximum control to the person ultimately building the downstream app (i.e. fish).

Sorry, wrong repo (I think). Re-opened here: fish-shell#2 |
