[Rust] SSL link errors with Sentry?

I’m trying to integrate Sentry with my (Rust) application but I keep getting SSL-related linker errors, such as:

  = note: /usr/bin/ld: /home/max/src/ul/services/target/debug/deps/libopenssl_sys-9d72d031aaceda91.rlib(openssl_sys-9d72d031aaceda91.openssl_sys.2sb60usr-cgu.7.rcgu.o): in function `openssl_sys::tls1::SSL_set_tlsext_host_name':

I’m using the sentry-0.18.1 crate, have SSL libraries and SDKs installed. I’ve tried both the native TLS feature as well as rustls and have had no success with either.
