-The above is useful, if you need to customize the `find_package` calls of FairMQ's dependencies. Check the next section for more CMake options.
+Of course, feel free to customize the above commands to your needs.

+Optionally, you can require certain FairMQ package components and a minimum version:

+```cmake

+find_package(FairLogger ${FairMQ_FairLogger_VERSION})
+find_package(Boost ${FairMQ_Boost_VERSION} COMPONENTS ${FairMQ_BOOST_COMPONENTS})
+```
