QtPDF not availabel on mac?

MuPDF is the best. PDFium(Qt) is second. XPDF(Poppler) is third. You choose the better one for your app. You need to pay attention to license issue.

@zhenghan Hi, sorry for late reply - I just built it from source, signed and installed. Like you did, from what I see.

I am successfully using PoDoFo from vcpkg for manipulating PDF (merging files, adding text content ,etc) files in my Qt 6.1 cmake project. Adding digital signatures with it should be possible ( I have read some code for it in the library but I don't have a use-case currently).
Be sure to install the [fontconfig] version of podofo otherwise you will get unexpected crashes on windows when drawing text with fonts.
Coding with it is quite straightforward although the documentation could be better - but I am no fluent c++ coder.
