Not sure, it's just for packages using GNUInstallDirs.cmake.

Well, it not work, here is the exact output by liblxqt:
By not providing "FindQt5Xdg.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "Qt5Xdg", but
CMake did not find one.
Could not find a package configuration file provided by "Qt5Xdg" with any
of the following names:
Qt5XdgConfig.cmake
qt5xdg-config.cmake
Add the installation prefix of "Qt5Xdg" to CMAKE_PREFIX_PATH or set
"Qt5Xdg_DIR" to a directory containing one of the above files. If "Qt5Xdg"
provides a separate development package or SDK, be sure it has been
installed.
Since FindQt5Xdg.cmake is not provided by upstream, it looks like we have to set
CMAKE_PREFIX_PATH or Qt5Xdg_DIR.
And if I understand correctly, at liblxqt side, since #:configure-flags can
not refer inputs, I have to add a pre-configure phase, then using setenv.

Yes, it not feeling good, but I have no better idea now.
