That must be outdated. I added some cmake code to rosjava to support this. 

Here is an example from cmake code that links to my "externalLibs" package, which simply consists of a "jar" directory, containing a bunch of .jar files and a .jnilib file: 

rosbuild_find_ros_package(externalLibs)
add_classpath(${externalLibs_PACKAGE_PATH}/jar)
add_runtime_classpath(${externalLibs_PACKAGE_PATH}/jar)
add_jar_dir(${externalLibs_PACKAGE_PATH}/jar)
add_jni_path(${externalLibs_PACKAGE_PATH}/jar)
