COMP: add FindJNI to build with OTB_WRAP_JAVA on precise

CMake/FindJNI.cmake

+# - Find JNI java libraries.
+# This module finds if Java is installed and determines where the
+# include files and libraries are. It also determines what the name of
+# the library is. This code sets the following variables:
+#   
+#  JNI_INCLUDE_DIRS      = the include dirs to use
+#  JNI_LIBRARIES         = the libraries to use
+#  JNI_FOUND             = TRUE if JNI headers and libraries were found.
+#  JAVA_AWT_LIBRARY      = the path to the jawt library
+#  JAVA_JVM_LIBRARY      = the path to the jvm library
+#  JAVA_INCLUDE_PATH     = the include path to jni.h
+#  JAVA_INCLUDE_PATH2    = the include path to jni_md.h
+#  JAVA_AWT_INCLUDE_PATH = the include path to jawt.h
