I have installed Taglibcpp library using nuget package manager in visual studio 2019. When I try to build the project, I get the following errors:

error LNK2019: unresolved external symbol "public: __cdecl TagLib::FileName::FileName(char const *)" (??0FileName@TagLib@@QEAA@PEBD@Z) referenced in function "public: __cdecl MainWindow::MainWindow(class QWidget *)" (??0MainWindow@@QEAA@PEAVQWidget@@@Z)

error LNK2019: unresolved external symbol "public: __cdecl TagLib::FileRef::FileRef(class TagLib::FileName,bool,enum TagLib::AudioProperties::ReadStyle)" (??0FileRef@TagLib@@QEAA@VFileName@1@_NW4ReadStyle@AudioProperties@1@@Z) referenced in function "public: __cdecl MainWindow::MainWindow(class QWidget *)" (??0MainWindow@@QEAA@PEAVQWidget@@@Z)

Looks like you did not link to the library for taglib. – drescherjm Jun 14 '20 at 13:55
so how to link, I thought that nuget automatically link to libraries – Mina Talaat Jun 15 '20 at 14:06
I think it sets up the paths but does not link to individual libraries in every project that you have. The automatic ones probably use #pragma comment(lib, libname.lib) in a header. – drescherjm Jun 15 '20 at 14:09
