Perhaps this is due to mix of the msys (inside octave) and msys2 (outside 
octave).
For octave build, the external libraries are only JAVA related things and their 
include files and
libraries  can be set in configure option like


../octave/configure 
--prefix=/c/usr/Tatsu/program/Octave/octaveBuild/4.1.0+/usr/local \
--disable-docs \
--with-java-homedir=/c/Program\ Files\ \(x86\)/Java/jdk1.8.0_91/bin \
--with-java-includedir=/c/Program\ Files\ \(x86\)/Java/jdk1.8.0_91/include \
--with-java-libdir=/c/Program\ Files\ \(x86\)/Java/jdk1.8.0_91/lib 

However the above can be used only for octave itself case.

 
At this moment, it is better to find compromising points to go further.


Second workaround is to add also LDFLAGS like

CPPFLAGS='-IE:/octave_dev/include/octave-4.1.0+ 
-IE:/octave_dev/include/octave-4.1.0+/octave' \
LDFLAGS='-L/e/ocgtave_dev/lib' \
./configure --with-octave=/e/octave_dev


(It may be required other -L<some lib dir> flag in LDFLAGS.)

We have to construct msys2 based system and
it also use config tools, include files and libraries in the octave directories.
(bin, include and lib)
I am at the moment very occupied with the jobs of my University so that
I cannot take the time for arrange better build environments.
