Also what W10 feature release YYMM and/or build NNNNN are you on?

Should this discussion perhaps be handled on cygwin-apps?
We don't always want to advertise just how messy the Cygwin package making
sausage factory can be. ;^>

I believe the following Cygwin tools and libraries packages, pulled from the
package doc build dependencies, and found and filtered using apt-cyg listall, to
be sufficient, but may not all be necessary, and should be added to
octave.cygport, where it can be used as a build dependency install package list
for apt-cyg or setup:

DEPEND="autoconf automake bison flex gcc-core gcc-fortran gcc-g++ gperf gnuplot
libtool make texinfo libopenblas liblapack-devel libpcre-devel libarpack-devel
libparpack-devel libcurl-devel libfftw3-devel libfltk-devel libfontconfig-devel
libfreetype-devel libglpk-devel libgl2ps-devel libGraphicsMagick-devel
libhdf5-devel libllvm-devel libportaudio-devel libQtOpenGL4-devel libqhull-devel
libqrupdate-devel libqscintilla2-devel libqscintilla2_qt4-devel
libqscintilla2_qt5-devel libqt3-devel libsuitesparseconfig-devel
libsundials-devel zlib-devel"

Are there any changes you would make, especially for arpack, OpenGL, qt, scintilla?
