The QP™/C++ <span class="img folder">src</span> directory needs to be added to the compiler's include path in the applications that build QP™/C++ framework from sources (as opposed to using QP as a pre-built library).
Typically, files in this directory need to be added to the application build, but some QP ports might not need all the files in this directory. For example, a QP port to a 3rd-party RTOS kernel might be using a message queue of the RTOS instead of the native QP event queue, in which case the file qf_actq.c would not be needed and should be excluded from the build.
