I'm pretty sure LINK_DIRECTORIES should not be used in toolchain
if not use at all.

The purpose of find_package is precisely to find the full path to libraries
thus not to need to use "LINK_DIRECTORIES".

Nope. you shoud throw away
INCLUDE_DIRECTORIES
and
LINK_DIRECTORIES
from your toolchain

and then retry in order to see what happen with find_package(OpenSSL)
proper setting of

CMAKE_FIND_ROOT_PATH* should makes it possible for FindOpenSSL to find
the lib.

By the way, which version of CMake are you using?
