I cannot figure out how to get this thing working. It keeps on
complaining when fed with an exe that I just build :
dpkg-shlibdeps: failure: no dependency information found for
/tmp/local/lib/libgdcmjpeg12.so.62.1 (used by
/tmp/local/bin/gdcmdump).

That's the thing I as asking for in the first place, will look into it, thanks.

I can tell cmake to package my own postinst/preinst file, eg:

I originally wrote the deb plugin, Alex simply integrated in cmake. If
you've lost the email, I'll check with them.

I had to look at what packages I had installed on my machine. Using
ldd I just selected a couple of them (I might be missing some).
As I said I could not figure out what tool was used to dump that
particular line in the control file.

ok
All this is kindda new to me. When I was looking at debian package
that use cmake to be build, I assumed the value in the control files
where hardcoded.
So, I changed my mind, I am not looking into deb-packaging my project
directly, but instead have the minimum debian specific files that
start cmake and in the end produce a valid/consistant .deb file. I was
suggest libopensync, is this a good start ?
Thanks again,

Ps: I had the discussion with Alex whether or not we should rely on
the dpkg-* tool to build a .deb file, since it appeared to me as being
only simply a 'ar' file , I assumed we could bypass them. Anyway
dpkg-shlibdeps seems to be a much more complex tool than just objdump
or ldd on the lib, this will be difficult to avoid.
