Qt – Qmake in release and debug mode

configqmakeqt

I have a library and I would like it to copy itself to a directory depending upon what configuration i'm in (debug or release). Here is my project file.

#-------------------------------------------------

TARGET = JECLibrary
TEMPLATE = lib

DEFINES += JECLIBRARY_LIBRARY

SOURCES += \
    JECMessageText.cpp \
    JECMessageCombo.cpp \
    JECButton.cpp

HEADERS +=\
        JECLibrary_global.h \
    JECMessageText.h \
    JECMessageCombo.h \
    JECButton.h

CONFIG(debug, debug|release)
{
    DLLDESTDIR += $$quote(../../../Jane/Jane/Build/debug)
    message("Copying to Jane Debug Directory.")
}
CONFIG(release, debug|release)
{
    DLLDESTDIR += $$quote(../../../Jane/Jane/Build/release)
    message("Copying to Jane Release Directory.")
}

FORMS += \
    JECMessageText.ui \
    JECMessageCombo.ui

For some reason, the debug or release DLL are copied to both directories instead of just one. So if I run in release mode, I get the release DLL in both the Debug directory and release directory.

I'm totally confused. Could someone shed some light on this? Thanks

The opening brace should be on the same line as the condition:

CONFIG(debug, debug|release) {
    DLLDESTDIR += $$quote(../../../Jane/Jane/Build/debug)
    message("Copying to Jane Debug Directory.")
}
CONFIG(release, debug|release) {
    DLLDESTDIR += $$quote(../../../Jane/Jane/Build/release)
    message("Copying to Jane Release Directory.")
}

or 

CONFIG(debug, debug|release) {
    DLLDESTDIR += $$quote(../../../Jane/Jane/Build/debug)
    message("Copying to Jane Debug Directory.")
} else {
    DLLDESTDIR += $$quote(../../../Jane/Jane/Build/release)
    message("Copying to Jane Release Directory.")
}

But both messages will be displayed, because the files Makefile.Debug and Makefile.Release are both created when you run qmake (on Windows, or if you add debug_and_release to the CONFIG variable on other OSes).
