In your CMakeLists.txt file:
set(Boost_USE_STATIC_LIBS ON)
find_package(Boost REQUIRED ...)
Where I have ..., you optionally put the names of the libraries you want to use, and then target_link_libraries(targetname ${Boost_LIBRARIES}) later below. If you have a fairly recent distribution of CMake, it should work exactly as advertised. I do it exactly this way in my own projects.
