Your boost ist not compiled to allow for static linking, you can use the install.sh script to download a precompiled boost version for you or compile it yourself with static linking support

I solved this by switching to the dynamic library using this patch.

Great!

We should probably be adding an option for that to our CMakeLists.txt ;)

I am trying to prepare an upload of opencamlib to Debian, and such option would be useful. Have met quite a few obstacles in the build process, this was just the first of them. :)

I am on IRC, #debian-science on irc.debain.org, if someone want to help out. :)
