How do I setup TagLib 1.11.1 as a static library for my Qt Creator project on OS X?

I am working on a C++ project in Qt Creator (on OS X), and I want to use TagLib. After much research online, I'm struggling to figure out how to get to a point where I can use the TagLib library in my project.

So far I have:

• Downloaded taglib-1.11.1.tar and unarchived the contents.
• Downloaded CMake and used the GUI to configure and generate these files. (I used the CodeBlocks - Unix options for this, as from what I have found this has been suggested)
• From here I have tried: a) Adding the generated files as an external library to my Qt Creator Project. However, this seems to just add ~ 3 lines to my current .pro file referencing the path of the TagLib files. b) Creating a new project specifically for this library... c) smashing my head against the wall trying to get this to work.

Any help with this would be much appreciated, thanks.

Edit:

When I add the external library, the following is added to my .pro file:

win32:CONFIG(release, debug|release): LIBS += -     L$$PWD/../../../Libraries/taglib-1.11.1/taglib/release/ -ltag
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/../../../Libraries/taglib-1.11.1/taglib/debug/ -ltag
else:mac: LIBS += -F$$PWD/../../../Libraries/taglib-1.11.1/taglib/ -framework tag
else:unix: LIBS += -L$$PWD/../../../Libraries/taglib-1.11.1/taglib/ -ltag

INCLUDEPATH += $$PWD/../../../Libraries/taglib-1.11.1/taglib
DEPENDPATH += $$PWD/../../../Libraries/taglib-1.11.1/taglib

I then run qmake, and the project builds & runs fine. However, if I attempt to do something like #include <tag.h>, I get an error. For this example, it says 'tstring.h' file not found #include "tstring.h". Then, when I delete the error line, it gives a different error when I run it framework not found tag linker command failed with exit code 1 (use -v to see invocation).

Edit:

code in .pro changed to:

#win32:CONFIG(release, debug|release): LIBS += -L$$PWD/../../../Libraries/taglib-1.11.1/taglib/release/ -ltag
#else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/../../../Libraries/taglib-1.11.1/taglib/debug/ -ltag
LIBS += -F$$PWD/../../../Libraries/taglib-1.11.1/taglib/ -ltag
#else:unix: LIBS += -L$$PWD/../../../Libraries/taglib-1.11.1/taglib/ -ltag

INCLUDEPATH += $$PWD/../../../Libraries/taglib-1.11.1/taglib
DEPENDPATH += $$PWD/../../../Libraries/taglib-1.11.1/taglib

Now I get the error library not found for -ltag.

Here is an image of the files under ../Libraries/taglib-1.11.1 and the options I used in CMake link.

Edit:

I installed in it using the following:

  cmake -DCMAKE_INSTALL_PREFIX=/usr/local -DCMAKE_BUILD_TYPE=Release
  make
  sudo make install

Now the directory of files in the library looks like the following. Then I re-added the external directory in Qt. So now my .pro file contains:

LIBS += -L$$PWD/../../../Libraries/taglib-1.11.1/taglib/ -ltag

INCLUDEPATH += $$PWD/../../../Libraries/taglib-1.11.1/taglib
DEPENDPATH += $$PWD/../../../Libraries/taglib-1.11.1/taglib

PRE_TARGETDEPS += $$PWD/../../../Libraries/taglib-1.11.1/taglib/libtag.a

Now it runs fine, unless I try to do something like #include <tag.h> and it gives the error 'tstring.h' file not found.

If you only build taglib without installing it.

You should have something along the lines of:

INCLUDEPATH += \
    /path/to/taglib_source/taglib \
    /path/to/taglib_source/taglib/toolkit \
    /path/to/taglib_builddir/

LIBS += \
    -L/path/to/taglib_builddir/taglib \
    -ltag

If you installed taglib using the defaults:

INCLUDEPATH += \
    /usr/local/include/taglib

LIBS += \
    -L/usr/local/lib \
    -ltag
