# Due to Linux shipping libiconv in libc, third-party software often forgets to
# explicitly look for and add -liconv when required.  On systems that use GNU
# ld this isn't always an issue as it will often be pulled in via an explicit
# library, but some systems have a stricter linker that will not pull in
# symbols via implicit dependencies, and so we need to explicitly link here.
#
# Ideally this would be done via CWRAPPERS_LDADD to avoid leaking into LDFLAGS
# but there is no concensus on that yet.
#
# USE_EXPLICIT_LIBDEPS is a package-settable variable for rare cases where the
# libraries need to be pulled in but we do not want to expose them by default.
