Summary:                    FindBoost cannot handle parallel boost installations
- Fixed version attached
Description: 
FindBoost.cmake cannot handle multiple boost versions. It does not pick the
include directory correctly, i.e. the version of the include directory does not
correspond to the version of the library directory. Example (/usr and custom
dir, here: /opt)
boost 1.40 installed in /usr/ and 1.44 in /opt/boost/  
Setting BOOST_ROOT to /opt/boost or alternatively BOOST_INCLUDEDIR and
BOOST_LIBRARYDIR to /opt/boost/include and /opt/boost/lib/ will result in: 
Boost_INCLUDE_DIR -> /opt/boost/include and Boost_LIBRARY_DIR -> /usr/lib and
Boost_SYSTEM_LIBRARIES .. /usr/lib/libboost..


Steps to Reproduce: 

Install boost into /usr/ and into /opt/boost, export BOOST_ROOT=/opt/boost or
BOOST_INCLUDEDIR=/opt/boost/include, BOOST_LIBRARYDIR)/opt/boost/lib and run a
CMake project with

find_package(Boost 1.38 COMPONENTS filesystem system unit_test_framework thread
serialization)

message(${Boost_INCLUDE_DIRS})
message(${Boost_LIBRARY_DIRS})



Additional Information: 
Attached the update FindBoost.cmake version that first searches the provided
path with NO_DEFAULT option and has a fallback to the DEFAULT path search. It
also provides full path information on the found libraries.
