Description

Mac OS X 10.7 and newer don't come with Java installed. They do include some stub binaries, which ask the user if they want to install Java when run.

OpenCV's cmake script just checks for the existence of an ant binary and appears to assume that Java's available if ant is. As a result, cmake will configure the build to use Java and it will fail once it tries to compile the Java bindings.

This can be fixed by checking for the exit status of `ant -version` - it'll exit 0 if Java is installed, or 1 otherwise.

The user who reported this to me provided the attached patch.
