If it helps you in any way, we now (i.e. in 2.5.27.1 in git since commit

such that the default location it looks for camlibs and iolibs can be
set at configure time:
configure \
camlibdir=/where/to/install/the/camlibs \
DEFAULT_CAMLIBS=/where/to/find/the/camlibs \
iolibdir=/where/to/install/the/iolibs \
DEFAULT_IOLIBS=/where/to/find/the/iolibs
The defaults should be sane:
* If camlibdir= is not set at configure time, use a default location
based on ${libdir} to find out where to install the camlibs.
* If DEFAULT_CAMLIBS is not set at configure time, use the value of
${camlibdir} to find out where to look for the camlibs.
* Analogous behaviour for iolibs.
I think I tried one of those earlier, but discovered it has to be an
absolute path. The Python interface can legitimately be installed in one
of several different places, so a relative path is needed.
What we do not have at this time is a way to change the driver lookup
location at runtime with an API function call. That has been proposed
in https://github.com/gphoto/libgphoto2/pull/534 but I have
not thought much about it so far. I certainly do not want to hurry
changes to the public API and ABI as those tend to stick for a long
time.
I agree with you. I've got a working solution now so I'm happy if there
are no further changes.
