The bug is when you don't set BOOST_ROOT.  It detects the headers
(Boost_INCLUDE_DIR) but not the libraries.  It should either detect both the
headers & libraries or fail miserably causing the user to discover
BOOST_ROOT.  See below for more info.

If you can add the following to your

Here's the output (looks good).

Boost_LIB_VERSION: 1_36

boost_filesystem-vc80-mt-1_36

boost_filesystem-vc80-mt-1_36

boost_filesystem-mt

boost_filesystem-mt

boost_filesystem


 None of that output is the problem, here I think is the issue.  Somehow
Boost_FIND_VERSION_MAJOR, etc. looks to be being squashed?

_boost_LIBRARIES_SEARCH_DIRS =
C:/boost/lib;C:/boost;C:\Program Files/boost/boost___/lib;C:\Program
Files/Boost;/sw/local/lib

Here's the configuration:
CMake 2.6.2, BoostPro 1.36.0 (all VS8 libs installed), Visual Studio C++
2005 Express

Just unset BOOST_ROOT and hopefully you'll be able to reproduce it

CMakeLists.txt:
============
PROJECT(Foo)
FIND_PACKAGE(Boost COMPONENTS filesystem)

Cache variables are:
============
Boost_FILESYSTEM_LIBRARY_DEBUG = ...NOTFOUND
Boost_FILESYSTEM_LIBRARY_RELEASE = ...NOTFOUND
Boost_INCLUDE_DIR = C:/Program Files/boost/boost_1_36_0
Boost_LIB_DIAGNOSTIC_DEFINITIONS = -DBOOST_LIB_DIAGNOSTIC
Boost_USE_MULTITHREADED =On
