cmake can't find configuration file for QtPDF

I looked forward to test the new components to show PDF. So I install Qt5.15 from the maintenance tool. I tried to compile with QtPdf.

In my CMakeLists.txt file, I add "Pdf" on the find_package line.

find_package(Qt5 ${QT_REQUIRED_VERSION} CONFIG REQUIRED COMPONENTS Core Widgets Gui Svg Network Multimedia PrintSupport Qml Quick QuickWidgets Xml WebEngineWidgets Concurrent Pdf)

And cmake does not find any config file. There is no Qt5Pdf directory inside /my/install/of/Qt/5.15.0/gcc_64/lib/cmake/.

All other Qt modules have a directory there, but Qt5Pdf.

Regards.
