Verified. When I have 1.2.3 version's zlib.h, compilation succeeds.
When I only have 1.1.4 version's zlib.h, it fails.
Then, I have two questions or comments.
1) "Can't find system..." or "Could not find..."
This newly added code uses error messages with current tense. But some
other error messages (Qt, GMP etc) usees past tense. Isn't it better
to integrate messages?
2) Runtime checking.
Current build tries to link with libz.so rather than libz.a. This
means, if we execute binaries compiled with v1.2.3 of zlib but
executed with v1.1.4 of zlib may introduce some mysterious bug as
I first encounter.
If someone can add runtime checking for the version, it should be
Anyway, these two are very minor and we can leave them as they are
