Comment (by chrstphrchvz):

 transmission 4.0.0 added CommonCrypto support, but it requires
 CommonCrypto/CommonRandom.h which is only present on macOS 10.10 and
 later. And transmission only checks for CommonCrypto/CommonCrypto.h
 ([https://github.com/transmission/transmission/blob/4.0.3/CMakeLists.txt#L231]),
 which is present since macOS 10.8, before enabling CommonCrypto support.

 This issue may be resolved by specifying `-DWITH_CRYPTO=openssl` in
 `configure.args` so that OpenSSL is always used instead of CommonCrypto.
 transmission-x11 already depends on OpenSSL, and `-DWITH_CRYPTO=…` should
 be specified anyway to avoid opportunistically depending on other crypto
 implementations.
