Philip, does this apply to the latest release (i.e. cmake 2.6.4)? Or
rather the latest revision in CVS? (See also below)

Ok, so now I have installed Boost 1.40.0 with the following command:

...\boost_1_40_0>.\bjam --prefix=C:\Programme\boost
--build-type=complete install

(i.e. without version number in the prefix). Without any additional
help (for instance setting BOOST_ROOT) except
set(Boost_ADDITIONAL_VERSIONS "1.40" "1.40.0"), FindBoost emits:

Boost not in cache

Note that something similar to the actual BOOST_ROOT is in
_boost_INCLUDE_SEARCH_DIRS. Maybe the backslash in C:\Programme/boost
is wrong?

I'd propose to make FindBoost recursively searching the
_boost_INCLUDE_SEARCH_DIRS for the requested version. But maybe
FindBoost already does that and my problems just result from that
strange backslash...

Kind regards
