That could be done, as long as all the applications linking directly or
indirectly to liboauth link to a suitable libcurl too (i.e. leaving all the
libcurl symbols unresolved in liboauth). AFAICT this is currently not enforced
since e.g. oauth.pc only lists libcurl as Requires.private.
Directly depending on libcurl3* packages is of no use: either the application
links to a libcurl flavour, in which case it would already Depends on a suitable
libcurl3 package, or it doesn't and it wouldn't pick up the library even if
installed (unless forcibly loaded e.g. via LD_LOAD_LIBRARY, but that's not a
real solution).
Also note that libcurl3* libraries are not interchangeable, since they have
different SONAMEs and symbols versioning (i.e. once you link against one of
them at compile time, you have to use the same to resolve libcurl symbols at
load time).
Cheers
