I am using Qt Creator, Qt6, C++ for my program.
I would like to use the PoDoFo library but I have no knowledge of how to add the library/headers so that I can use it in my project and build it.
I have downloaded the PoDoFo code, just can't find any guidance/tutorials on how to add PoDoFo specifically in Qt Creator.
Edit: I tried "Add Library" to my project and used external library option. Once I finish, I try to compile my code and I get an error "podofo-0.9.7\COPYING.LIB:-1: error: LNK1107: invalid or corrupt file: cannot read at 0x62DC"
I can include the podofo.h file but that will also throw this error:"podofo-0.9.7\src\podofo\base\PdfCompilerCompat.h:44: error: C1083: Cannot open include file: 'podofo_config.h': No such file or directory"

Did you take a look on this link: https://doc.qt.io/qt-5/third-party-libraries.html?
I just followed it and my 3rdParty library (https://github.com/cutelyst/simple-mail) was linked and accessible from my application C++.
Basically, your .pro file will look like this after setting everything properly:

i'm trying to make a QT Widgets project. I have to use a "libpng" library, but i'm having a trouble including it. Here is the config .pro file.

This is the solution, which worked for lots of people (found it somewhere), but has no result for me. When i try to include it in main.cpp file, this error pops up:
'png.h' file not found
#include "png.h"
^~~~~~~
How can i fix it?
The solution was pretty simple. I made a mistake in the root to "libpng".
I had to change my 2 lines of code:
INCLUDEPATH += /usr/local/include
LIBS += -L/usr/local/lib/libpng
I request your knowledge about QT.
Do you know why during the compilation a moc file cannot find include from QT ?
I currently have this problem in Qt Project, the error is
"moc_SettingsDialog.cpp:9: In file included from moc_SettingsDialog.cpp:9:
SettingsDialog.h:12: error : 'QDialog' file not found".
