Alex,

You can see which Boost version Cmake is finding for you by looking at
CMakeCache.txt in the top of the build directory. Check out the
"Boost_<library>_LIBRARY" and "Boost_INCLUDE_DIR" to see which ones
were found and are being used. Hopefully, it's finding the 1.48
version that's installed.
