If Boost is always needed

find_package(Boost REQUIRED)
add_executable(progname file1.cxx file2.cxx) 
target_include_directories(progname PRIVATE ${Boost_INCLUDE_DIRS}) 
target_link_libraries(progname PRIVATE ${Boost_LIBRARIES})

If Boost is optional

find_package(Boost)
if(Boost_FOUND)
    add_executable(progname file1.cxx file2.cxx) 
    target_include_directories(progname PRIVATE ${Boost_INCLUDE_DIRS}) 
    target_link_libraries(progname PRIVATE ${Boost_LIBRARIES})
endif()

If you need specific libraries from Boost:

find_package(Boost COMPONENTS stuff)

e.g.

find_package(Boost COMPONENTS filesystem regex)
