What is the general wisdom when deciding whether to add support for
a new "-with" vs. just encouraging use of CFLAGS/LDFLAGS on the
command line?
A problem with the "-with" approach is that it is impossible to
achieve the flexibility offered to the user by CFLAGS/LDFLAGS and so
something is bound to lose. For example, ordering of options in
CFLAGS/LDFLAGS can influence which headers/libraries are used if there
are multiple versions in multiple directories, but the "-with"
approach hard-codes the ordering in the configure script where the
user can't do anything about it (other than using CFLAGS/LDFLAGS).
