The INSTALL_NAME_DIR property of a target specifies how a dynamic library should
be found on OS X.  If INSTALL_NAME_DIR is not specified the loader will search
relative to the standard search paths.  If specified it should either be
an absolute path or relative path prefixed with either @executable_path,
@load_path, or @rpath.  Specifying "lib" does not make sense here and
causes linking error as documented here:

This patch removes INSTALL_NAME_DIR everywhere it is set to "lib".
An alternate solution would be to set an absolute path like
"${CMAKE_INSTALL_PREFIX}/lib" or relative path like
"@executable_path/../lib".  However, if there is not specific need for
specifying a path, it is probably best left unset.

Fixed "Conditional jump or move depends on uninitialised value(s)" valgrind issue due to wrong pointer recalculation for zero level of pyramid.

Removed ioctl calls to query for VIDIOC_G_INPUT and VIDIOC_ENUMINPUT since information returned by the calls is never used.
Fixed icvCaptureFromCAM_V4L return value in case of V4L2 camera initialization failure.
