[CMake] Problems finding the SSL library

Hello everyone,

I'm attempting to build mysql-5.5. It fails while finding the OpenSSL
library, and I can't figure out why. All other problems can find
OpenSSL without any problems.

The source code:
http://ftp.heanet.ie/mirrors/www.mysql.com/Downloads/MySQL-5.5/mysql-5.5.19.tar.gz

Here's what the build attempt looks like. Note how the environment is
controlled by invoking /usr/bin/env -i which cleans the environment,
and then explicitly setting all the environment variables.

...so the library + .so symlink look ok.

My journey so far was this:

- I contacted the mysql IRC channel and was told that something's
wrong with cmake
- I contacted the cmake IRC channel and was told that something's
wrong with mysql
- I was given some debugging commands, flags, and environment
variables but none of that helped
- I tried to work out what exactly is cmake doing, and it turned out
to be quite opaque
- I looked into the CMakeError.log file and found this:

The relevant compiler command is:

It fails with line 2: "cannot find include file: <openssl/sha.h>"

...but the compiler invocation is missing -I/opt/csw/include.

"-DOPENSSL_ROOT_DIR=/opt/csw" is set as one of the cmake flags. Also,
there's an environment variable: CPPFLAGS="-I/opt/csw/include", but it
doesn't seem to be processed by cmake.

Please don't send me away saying that the MySQL macros are at fault.
Maybe they are! But I've already tried[1] asking there and got no
answer. I need to find out what exactly is cmake doing and how can I
tell it that it needs to add -I${prefix}/include to the compiler
invocation if OpenSSL is at ${prefix}.
