configure fail if libssl is named libssl-opt

Hello,

I try to build dovecot with my own version of openssl. It's compiled in a way the libraries can coexist without symbol conflict with the real OpenSSL in /usr: They are named libssl-opt and libcrypto-opt.

Now configure fail to find my libssl-opt:

CFLAGS="..." CXXFLAGS="..." CPPFLAGS="..." LDFLAGS="..." SSL_LIBS='-lssl-opt -lcrypto-opt' ./configure ... --with-ssl=openssl
...
checking for SSL_read in -lssl... no
configure: error: Can't build with OpenSSL: libssl not found

Is there an other way to tell configure the ssl libraries have other names?
