My method doea not work for fetchmail 7 alpha. It looks like it does not support openssl 3.x yet.

/tmp/fetchmail-7.0.0-alpha9/socket.c:997: undefined reference to `SSL_load_error_strings'
/tmp/fetchmail-7.0.0-alpha9/socket.c:998: undefined reference to `SSL_library_init'
/tmp/fetchmail-7.0.0-alpha9/socket.c:999: undefined reference to `OpenSSL_add_all_algorithms'
/tmp/fetchmail-7.0.0-alpha9/socket.c:1000: undefined reference to `SSLeay'

The rpm I have right now is really only suitable for a static openssl that gets built on the fly. I can get that part working after a fashion by manually modifying the fetchmail Makefile after configure.
