• create a test cmake project
• build it
• close the project
• remove the CMakeLists.txt.user file
• open the project in Qt Creator
• either the exisiting build is automatically found, or choose it for "import"
• configure the project

Expected: The project is opened and parsed.
Actual: The project is just opened, but the not parsed - the tree just shows the project node and CMakeLists.txt. Manually doing Build > Run CMake fixes that.
