+ECMQueryQt
+---------------
+This module can be used to query the installation paths used by Qt.
+
+For Qt5 this uses ``qmake``, and for Qt6 this used ``qtpaths`` (the latter has built-in
+support to query the paths of a target platform when cross-compiling).
+
+This module defines the following function:
+::
+
+    ecm_query_qt(<result_variable> <qt_variable> [TRY])
+
+Passing ``TRY`` will result in the method not making the build fail if the executable
+used for querying has not been found, but instead simply print a warning message and
+return an empty string.
+
+Example usage:
+
+.. code-block:: cmake
+
+    include(ECMQueryQt)
+    ecm_query_qt(bin_dir QT_INSTALL_BINS)
+
+If the call succeeds ``${bin_dir}`` will be set to ``<prefix>/path/to/bin/dir`` (e.g.
+``/usr/lib64/qt/bin/``).
