+
+Fixes <https://git.jami.net/savoirfairelinux/jami-client-qt/-/issues/882>.
+
+* tests/CMakeLists.txt: Add "Widgets" Qt module to find_package call.
+(QML_TEST_LIBS): Add Qt::Widgets.
+* tests/CMakeLists.txt: Rename QML_LIBS to QT_LIBS, a regression
+introduced in d82e3820706214d15d7cb7462978b7a43b798355.  Remove the
+dependency on on the Widgets module, now provided via QT_LIBS.
+* tests/qml/main.cpp [WITH_WEBENGINE]: Include QtWebEngine modules
+conditionally.
+(main) [WITH_WEBENGINE]: Initialize webengine conditionally.
+* tests/CMakeLists.txt: Link test objects with ${LIBCLIENT_NAME}.
+* src/app/qmlregister.h (registerTypes): Change parent type from
+MainApplication* to QObject*
+* src/app/qmlregister.cpp (registerTypes): Likewise.
+* tests/unittests/account_unittest.cpp (globalEnv): Remove variable.
+* tests/unittests/contact_unittest.cpp: Likewise.
