# JNI header generation is satisfied by above 'add_jar(.. GENERATE_NATIVE_HEADERS <target> DESTINATION <dir>)',
# note that its GENERATE_NATIVE_HEADERS target is a dummy target, since jni/direct_bt defines target javadirect_bt.
# Weakness of not directly checking build dependency of javadirect_bt against generated headers exists,
# however, it is unrealistic to assume that the transient generated JNI header will be edited manually
# within the process.
# Therefor we can use the dummy target javadirect_bt_javah and JNI header generation will only
# occur when java sources have been modified, i.e. the jar file being actually build.
