Good day. There is a QT 5.4 bundle with static linking libraries. Separately collected qtserialport. Tell me how to add this library to the project now in a standard way - through the .pro file?
QT += core serialport
You can of course connect manually via LIBS + = & INCLUDEPATH + =, but this is not an option, since in debug mode, one version of the library is needed, and in release mode, another is needed.
