+The detection uses pkg-config on Linux by default. The list of
+libraries to be requested to pkg-config is formulated by scanning
+in the QTLIBS directory (that can be passed via --qtlibs or by
+setting the environment variable QT5_LIBDIR otherwise is derived
+by querying qmake for QT_INSTALL_LIBS directory) for shared/static
+libraries present.
+Alternatively the list of libraries to be requested via pkg-config
+can be set using the qt5_vars attribute, ie:
+
+      conf.qt5_vars = ['Qt5Core', 'Qt5Gui', 'Qt5Widgets', 'Qt5Test'];
+
+This can speed up configuration phase if needed libraries are
+known beforehand, can improve detection on systems with a
+sparse QT5 libraries installation (ie. NIX) and can improve
+detection of some header-only Qt modules (ie. Qt5UiPlugin).
