Fix ant/Java detection in cmake scripts 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 assumes 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 fixes the issue by checking for the exit status of `ant -version` - it exits 0 if Java is installed, or 1 otherwise.
