find_package(Boost 1.75 REQUIRED COMPONENTS filesystem system) if(Boost_FOUND) target_link_libraries(my_app PRIVATE Boost::filesystem Boost::system) endif() CMake will automatically search standard system paths, or paths you hint via -DCMAKE_PREFIX_PATH . Not every library provides CMake configs. For those, you can use pkg-config (common on Linux): clion add external library

The IDE’s CMake cache viewer will show you exactly where FetchContent stored the library ( cmake-build-debug/_deps/ ), and code navigation works instantly.
