I'm using the latest SVN revision of libwebcam and uvcdynctl (as of two days ago) on Ubuntu 7.10, and I'm having an issue where the installed version of uvcdynctl is unable to load the libwebcam library:

$ /usr/local/bin/uvcdynctrl -l
uvcdynctrl: error while loading shared libraries: libwebcam.so.0.1.1: cannot open shared object file: No such file or directory

If I run the binary in the build/Apps/uvcdynctl/ directory after building with cmake it all seems to work fine, however:

$ ./uvcdynctrl -l
[libwebcam] Unknown V4L2 control ID encountered: 10094851
Listing available devices:
video0 UVC Camera (046d:0990)

This is the same issue that was mentioned in a previous thread (http://forums.quickcamteam.net/showthread.php?tid=33) but that thread ended with the assumption that switching to cmake would fix the problem.

As I said before, I'm using:
libwebcam 0.1.1
uvcdynctl 0.2
cmake 2.4-patch 7

Thanks for any help you can provide.

I've added some hints to the README file. Can you give the part about changing the install prefix and/or LD_LIBRARY_PATH a try?

Setting LD_LIBRARY_PATH to include /usr/local/lib worked fine. I didn't try reinstalling with the different prefix.
