Summary:                    components are append to Boost_LIBRARIES
Description: 
When using FindBoost in the same CMakeLists.txt and with different components,
the variable Boost_LIBRARIES contains the union of the components.

I think that Boost_LIBRARIES variable should be cleared when each time
find_package(Boost ...) is invoked, or perhaps the doc should mentioned this
behavior.

Steps to Reproduce: 
cmake_minimum_required(VERSION 2.8 FATAL_ERROR)

project(foo)

find_package(Boost COMPONENTS thread)
message("boost libs: ${Boost_LIBRARIES}")

find_package(Boost COMPONENTS date_time)
message("\nboost libs: ${Boost_LIBRARIES}")

# the result is:
# boost libs: /usr/lib/libboost_thread-mt.so
#
# boost libs: /usr/lib/libboost_thread-mt.so;/usr/lib/libboost_date_time-mt.so

# but I think it should be:
# boost libs: /usr/lib/libboost_date_time-mt.so
