TagLib linking error Qt

Hello programmers!

I am builded TagLib 1.11.1 library with cmake for MinGW, installed it and connected to my Qt project:

INCLUDEPATH += \
"C:/Program Files (x86)/taglib/include/taglib" \

LIBS += \
-L"C:/Program Files (x86)/taglib/lib" -llibtag

But after running my program i get following errors:
In function `Z5qMainiPPc':
undefined reference to `_imp___ZN6TagLib8FileNameC1EPKw'
undefined reference to `_imp___ZN6TagLib7FileRefC1ENS_8FileNameEbNS_15AudioProperties9ReadStyleE'
undefined reference to `_imp___ZN6TagLib7FileRefD1Ev'
collect2.exe: error: ld returned 1 exit status

What's wrong, please help!
