[CMake] CMake toolchain and FIND_PACKAGE(OpenSSL)

Hi Vyacheslav,

You are right. It seems that removing LINK_DIRECTORIES does the trick!

If I throw the INCLUDE_DIRECTORIES directives way, CMake runs fine but the
project fails to compile. If I leave the (1st) INCLUDE_DIRECTORIES directive,
then every "works" as expected.

The only difference between both versions, is in the latter the flag -isystem
is passed to the compiler. That seems to make a huge difference at the end.

Of course, if there is a more sensible way do achieve the same result, I'd glad
to "ear" it.

Sorry, I forgot to mention the obvious. I am using CMake 2.8.3.
