Boost graph in CMake

Hi.

I'm having trouble with CMake boost find: It complains that it can't
find boost. Last time I just removed the "COMPONENTS graph" from
FIND_PACKAGE.

I did made a fresh checkout and now I decided to look at bit deeper.
Using Boost_DEBUG true it seems like cmake is probing for dll files
with patterns like boost_graph*

And, the FindBoost.cmake states that

# The components list needs to contain actual names of boost libraries only,
# such as "date_time" for "libboost_date_time".  If you're using parts of
# Boost that contain header files only (e.g. foreach) you do not need to
# specify COMPONENTS.
#

Sounds like the "COMPONENST graph" must be removed. How is it working
at all? Or is it only windows problem?

I've added this as boost graph is a real library on linux:

languitar@herbie:~$ ls -l /usr/lib/libboost_graph*
-rw-r--r-- 1 root root 629114 2010-05-08 02:53 /usr/lib/libboost_graph.a
lrwxrwxrwx 1 root root     16 2010-11-08 21:13
/usr/lib/libboost_graph-mt.a -> libboost_graph.a
lrwxrwxrwx 1 root root     24 2010-11-08 21:13
/usr/lib/libboost_graph-mt.so -> libboost_graph.so.1.42.0
lrwxrwxrwx 1 root root     24 2010-11-08 21:13
/usr/lib/libboost_graph.so -> libboost_graph.so.1.42.0
-rw-r--r-- 1 root root 303600 2010-05-08 02:53
/usr/lib/libboost_graph.so.1.42.0

Normally it should also be one on windows? Is there really no
boost_graph.dll or something like this? Is boost graph really built by
your installation?

No boost_graph dll... Not sure if it is built or not, or if it
needs/supports building on windows. Didn't build boost manually but
with emerge.

But the graph headers are definitely present in boost include directory.

Ok, I checked the boost documentation. The library file is optional and
only required to parse graphviz files. So the component request can be
removed from the cmake script.

Sorry,
