Cannot be done - if you want to have libev only, you should build libev,
not the perl module, as the resulting binary libev depends on perl.

If you want to use the testsuite for EV, you should use the resulting perl
module (it has a C API), but of course that requires perl in your binary
somewhere then.

Your request is sane, but hardly doable on windows, as libev built for
perl necessarily has a different ABI (and requires the perl runtime
support) then the one built standalone.

(And yes, that's all due to both microsoft not having a standard C ABI and
microsoft not following POSIX, which emans all programs have to implement
soem glue code to their env, and that glue code is inside perl for EV, and
inside your program for standalone builds).
