Hello,
on unix* hugin stores functions used by multiple executables in
private shared libs. This is done to minimize the size of
executables.
However afaict these libraries are not supposed to be used by programs
outside hugin. Nobody seems to be responsible for defining and
monitoring a public interface. The libraries are not versioned. Stuff
should just work for hugin.
This is not to be read as criticism, I am just trying to provide a
rationale why I think the libraries are private.
Anyway, how about making this fact [1] a little bit more official by
moving the libs to a private subdirectory ($libdir/hugin) and using
rpath?
Suggested patch attached.

[1] "If you use these shared libraries in your external program you
may keep both pieces when it breakes. Recompilation after every new
hugin release will probably be necessary. The API and ABI may change
without notice in an incompatible way (symbols removed, size of struct
changed, etc.) from one release to the next."

Install hugin shared libraries in a private subdirectory of $libdir and use rpath to let the dynamic linker locate them.
