-) Make sure you have libxvidcore4 and libxvidcore4-dev
-) Make sure you have libv4l-dev
-) NEW: Make sure you have CImg library (cimg-dev). For wxcam versions >= 1.0.5, use at least cimg version 1.33. For older version, use CImg 1.2.
-) NEW: Make sure you have mjpegtools (libmjpegtools-dev)
-) NEW: Make sure you have alsa developement (libasound2-dev)

-) Note for 64 bit systems: If you encounter the error "int_64 was already declared in this scope" in file mjpeg_types.h, this is a bug of mjpeg library. To overcome this bug, simply comment row 40 of your mjpeg_types.h file (ubuntu puts it in /usr/include/mjpegtools/mjpeg_types.h).
