Hi,

unset(Boost_INCLUDE_DIR CACHE) does not work either.
I have also tried to unset the following:

unset(Boost_INCLUDE_DIR CACHE)
unset(Boost_INCLUDE_DIR)

unset(Boost_INCLUDE_DIRS CACHE)
unset(Boost_INCLUDE_DIRS)

unset(Boost_FOUND CACHE)
unset(Boost_FOUND)

unset(Boost_LIBRARIES CACHE)
unset(Boost_LIBRARIES)

unset(Boost_LIBRARYDIR CACHE)
unset(Boost_LIBRARYDIR)

unset(Boost_VERSION CACHE)
unset(Boost_VERSION)

unset(Boost_NAMESPACE CACHE)
unset(Boost_NAMESPACE)

All to no avail. Not sure where to go from here (except debug it).

My cmake version is 2.8.12.2.

Regards,
Matt
