Using Taglib library with Qt

[eswar]

Thanks Lukáš and Joel for the replies.

Using TAGLIB_STATIC does the job here.

Just wondering if the default .pro file present does not do the job ?
Maybe it can be replaced with the one Joel has got it working for ? By
replacing those absolute paths ?

Thanks,
Eswar
