I am trying to install Octave-4.0.0 from source following the instructions from the wiki page. I have installed every single dependency (optional too) mentioned on that page. In the configuration step I used

./configure CPPFLAGS=-I/usr/include/hdf5/serial \
            LDFLAGS=-L/usr/lib/$(dpkg-architecture -qDEB_HOST_MULTIARCH)/hdf5/serial

as given there to avoid potential HDF5 library related problems. Doing this, I got (initially I was getting JAVA_HOME warning, which I then fixed):

configure: WARNING: Include file <jni.h> not found.  Octave will not be able to call Java methods.
configure: 
configure: NOTE: Libraries or auxiliary programs may be skipped if they are
configure: NOTE: not found OR if they are missing required features on your
configure: NOTE: system.

Thereafter, to fix this, I tried using how to add jni.h and adding libraries to ./configure path. But, if I follow that configure command with 

./configure CPPFLAGS=-I/usr/lib/jvm/java-7-openjdk-amd64/include

or even use both the CPPFLAGS settings together (that is, in the same ./configure line), I get this:

configure: WARNING: HDF5 library not found.  Octave will not be able to save or load HDF5 data files.
configure: WARNING: Include file jni.h not found.  Octave will not be able to call Java methods. 
configure:   
configure: NOTE: Libraries or auxiliary programs may be skipped if they are
configure: NOTE: not found OR if they are missing required features on your
configure: NOTE: system.

How should I pass these warnings and install Octave-4.0.0 gracefully (target: image processing)?

If you try to define multiple CPPFLAGS variables on the command line, only the last one will apply. Instead, you should be able to combine both include directives into a single variable as a quoted string:

CPPFLAGS="-I/usr/include/hdf5/serial -I/usr/lib/jvm/java-7-openjdk-amd64/include"

e.g.

./configure \
  CPPFLAGS="-I/usr/include/hdf5/serial -I/usr/lib/jvm/java-7-openjdk-amd64/include" \
  LDFLAGS=-L/usr/lib/$(dpkg-architecture -qDEB_HOST_MULTIARCH)/hdf5/serial
