If you're building 32 and 64 bit on the same machine, then at least of 
one these is cross-compilation.
With CMake (and other build systems), cross-compilation cannot happen 
automatically, you have to specify manually which directories to use to 
find libraries. Using the default may easily result in conflicts with 
the native libraries installed.

This is not a Boost-specific problem, this will affect any use of a find 
module and even find_library.

Boost_DIR, BOOST_ROOT, BOOSTROOT, BOOST_INCLUDEDIR and BOOST_LIBRARYDIR 
are all documented.
