Notice this change in search path, dll files in Windows are executables
and they are (must) installed in the system PATH (or the current
directory).
$PATH contains /usr/bin
Either that or python needs the symbols file, like the linker, which in
this case would be /usr/lib/liblept.dll.a, which is in the -devel
package, but I doubt it.
Installing the -devel package, and undoing my "fix" to leptonica.py
fixed the problem. I guess I'm now going to have to learn how to
build a Cygwin package for it.
the usage of import library for linking a library is very standard,
not really Cygwin specific.
headers and import library are almost every time in the libXXX-devel.
In the doubt you can look at the source package info:
https://cygwin.com/packages/summary/leptonica-src.html
Unfortunately I didn't realize how involved building it on Cygwin was
going to be and that it would be worth documenting, so I didn't keep
track of everything I had to do (sigh!)
building for Cygwin is a Unix-like exercise.
May be you started with a Windows-like view ?
How would I gauge interest in having a Cygwin version of OCRmyPDF?

ghostscript \

unpaper
the only package NOT available on Cygwin is "unpaper"
