Trying to understand the .Pro File

[EatonCode]

I am trying to understand how to include files based on the target Platform using the .pro file

I wish to create a program on the Win, Linux and MacOS.

But when I use this code in the .pro file it seems to include the files twice.

if (win32){

    isEmpty(QTITANDIR):QTITANDIR = '$$PWD/../resources/thirdparty/Win/Developer Machines/QtitanRibbon'
}

if (mac) {
    QMAKE_MAC_SDK = macosx10.12
    isEmpty(QTITANDIR):QTITANDIR = '/Users/eatoncode/Documents/QtitanRibbon'
}

if (linux)
{
    isEmpty(QTITANDIR):QTITANDIR = 'I:/Program Files (x86)/Developer Machines/QtitanRibbon'
}

it compiles without error but it seems to include 2 times.., the win32 and linux paths are the same the windows machine.. on is absolute and the other is relative. Even so on windows 10 it should only match 1 time.

What am I doing wrong ?

@EatonCode Please read http://doc.qt.io/qt-5/qmake-project-files.html
You're doing it wrong:

win32:INCLUDEPATH += "C:/mylibs/extra headers"

hi, friend, I shared the code from my project for you.

win32 {
    CONFIG(debug, debug|release) {
        DEFINES += DEBUG
    }

    CONFIG(release, debug|release) {
    }
    INCLUDEPATH  += "other include directory"
}

linux {
    CONFIG(debug, debug|release) {        
    }

    CONFIG(release, debug|release) {
    }
}

mac {
    CONFIG(debug, debug|release) {        
    }

    CONFIG(release, debug|release) {
    }
}

@jsulm Thanks for the link I think I understand.....

If I want to include one line I can use this method..

win32:INCLUDEPATH += "C:/mylibs/extra headers"

@joeQ Also thanks for the code snippet.

I assume I can use this code to include many lines of code to include.. Also include debug or release code . This is very handy when including libs from a third party..

win32 {
    CONFIG(debug, debug|release) {
        DEFINES += DEBUG
	isEmpty(QTITANDIR):QTITANDIR = '$$PWD/../resources/thirdparty/Win/Debug/Developer Machines/QtitanRibbon'
    }

    CONFIG(release, debug|release) {
	isEmpty(QTITANDIR):QTITANDIR = '$$PWD/../resources/thirdparty/Win/Release/Developer Machines/QtitanRibbon'
    }

        
}

linux {
    CONFIG(debug, debug|release) {
        DEFINES += DEBUG
	isEmpty(QTITANDIR):QTITANDIR = '$$PWD/../resources/thirdparty/Linux/Release/Developer Machines/QtitanRibbon'
    }

    CONFIG(release, debug|release) {
	isEmpty(QTITANDIR):QTITANDIR = '$$PWD/../resources/thirdparty/Linux/Debug/Developer Machines/QtitanRibbon'
    }

}

mac {
    QMAKE_MAC_SDK = macosx10.12

    CONFIG(debug, debug|release) {
        DEFINES += DEBUG
	isEmpty(QTITANDIR):QTITANDIR = '$$PWD/../resources/thirdparty/OSX/Release/Developer Machines/QtitanRibbon'
    }

    CONFIG(release, debug|release) {
	isEmpty(QTITANDIR):QTITANDIR = '$$PWD/../resources/thirdparty/OSX/Debug/Developer Machines/QtitanRibbon'
    }
}

Thanks.
