Qt5: Poppler weird linker error - c++

Question

I downloaded pre-built win32 poppler binaries from this page. Added the path for the include folder and lib folder in the .pro file:
INCLUDEPATH += "C:\\test_folder\\poppler-0.24.5-win32\\include\\poppler-qt5"
LIBS += -L/"C:\\test_folder\\poppler-0.24.5-win32\\lib"
In main.cpp i include "poppler-qt5.h" without errors, so I would think that poppler was added correctly. However when testing it by opening a pdf file, as described here,
QString path = "C:\\Windows\\System32\\spool\\PRINTERS\\test_file.pdf";
Poppler::Document *doc = Poppler::Document::load(path);
I receive a linker error:
Can someone help me out here?

Answer 1

I am missing the -l in yout LIBS line
LIBS += -L/"C:\\test_folder\\poppler-0.24.5-win32\\lib" -lpoppler-qt5
Eventually rename the lib since .dll.a is not a standard extension in windows.
Edit: Works without renaming the library:
.pro File:
INCLUDEPATH += $$quote(D:\Users\username\Downloads\poppler-0.24.5-win32\poppler-0.24.5-win32\include\poppler-qt5)
LIBS += -L$$quote(D:\Users\username\Downloads\poppler-0.24.5-win32\poppler-0.24.5-win32\lib) -lpoppler-qt5
.cpp File:
#include <QApplication>
#include <mycpp.h>
#include <poppler-qt5.h>
/* Some Code here */
QString path = "D:\\SomePDF.pdf";
Poppler::Document *doc = Poppler::Document::load(path);
/* More Code here */

I had the same problem and I resolved it with this method:
Copy dll file if you find in folder \poppler-0.24.5-win32\bin\ to folder where Qt generate executable file. Then download zlib1.dll and insert this dll to folder where Qt generate executable file. Try now.
This works for me. I compiled with qt 5.3 in Windows XP SP3.
