*-sys crates reminder #30

Open gyakovlev opened 4 years ago

gyakovlev commented 4 years ago

-sys crates often try to link to system libraries, and if not found will compile own private copy. notable examples are libgit2-sys (uses unreleased ABI and will fail at runtime if tries to link to system library), but requires setting LIBGIT2_SYS_USE_PKG_CONFIG=1 to force looking for it. onig-sys, will try to link to system oniguruma if it's found, and will compile private version if not. prcre2-sys, will try system, and will compile own static if not found. and more.

is it possible to modify cargo-ebuild to place a reminder if -sys crate is found in the depgraph? so users should check.

Yes. A patch for the exact wording you'd like would be preferred.
