I reproduced your problem on my 10.0 machine and resolved it by adding 'system' to the list of the components.

That was it - adding system to CMake fine_package() fixed the problem. I guess the entire build system was different, FreeBSD 9, gcc, boost 1.48, on my older system.

The dependency on System from Filesystem arrived sometime in the last 1.4x series. There's a bunch of them in Boost and some are even documented at times. Popular ones tend to be Thread+System, DateTime, Regex.
