QtPDF binaries are provided via Marketplace for convenience; but you can also build it yourself from the qtwebengine repo.
Building the current version
$ git clone https://code.qt.io/qt/qtwebengine.git
$ cd qtwebengine
$ git submodule update --init --recursive
$ qmake . -- -no-build-qtwebengine-core

Note: QtWebEngine build is disabled by user.
Note: The following modules are not being compiled in this configuration:
webenginecore
webengine
webenginewidgets
Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into '/usr'.
$ make && make install
First it builds tools if necessary (gn and ninja), then QtPDF. (If you don't give the -no-build-qtwebengine-core argument, it will spend a lot of time building QtWebEngine before building QtPDF.)
Examples are in examples/pdf and examples/pdfwidgets.
Historical repository
The older version in the Qt Labs QtPDF repository still exists, but development now continues in the qtwebengine repository. This was prompted mainly by the upstream Chromium switch of build system from gyp to gn system: it was some work to get qtwebengine building with that. Chromium (and thus Qt WebEngine) include PDFium already; so it was easier to build QtPDF from there than to fix the build in the other repository.
