Cpp qt: qmake

QMake is Qt's build system. It is dramatically simpler to build pure-Qt projects with than cmake, but 3rd party tools are less likely to support it (linters, 3rd party modules, etc).

I have not tested this anywhere but linux, but I expect it would work on windows/macosx.

project/
     includes/
         mybutton.h
     src/
        main.cpp
        mybutton.cpp
    main.pro

main.pro

QT       += widgets core gui
SOURCES  += src/main.cpp src/mybutton.cpp
HEADERS  += include/mybutton.h
INCLUDEPATH += include
TARGET    = bin/main
BUILD_DIR = build
