+# qtcrator workaround for missing files in project
+# ========================================================================
+
+# qtcreator (4.0.3) does not include some header files and *T.cc in its
+# project structure. The issue is well-known, this is a workaround.
+# Unfortunately I could not find a workaround that does not involve adding
+# a dummy target that is visible in the target list.
+
+# To force adding files to the project structure, use
+# target_sources(_qtcreator_add_files PUBLIC ${EXTRA_FILES})
+# in your CMakeLists.txt
