Clion won't index auto-generated ui header files

I was having a look at the KeepassXC's source code, with Clion as my IDE of choice. After a bit of digging and navigating through the source code, I noticed that one of the source file has the following #include directive:

#include "ui_MainWindow.h"

with a red underline. Hovering over it with my mouse, it says "'ui_MainWindow.h' not found".

The project's CMakeLists.txt file provides three build types:

and, once all three build types are successfully built, the file CLion should look for is in the following location:

cmake-build-(debug|release|relwithdebuginfo)
└── src
    └── keepassx_core_autogen
        └── include
            ├── moc_KMessageWidget.cpp
            ├── ui_AboutDialog.h
            ├── ui_CategoryListWidget.h
            ├── ui_ChangeMasterKeyWidget.h
            ├── ui_CloneDialog.h
            ├── ui_CsvImportWidget.h
            ├── ui_DatabaseOpenWidget.h
            ├── ui_DatabaseSettingsWidgetEncryption.h
            ├── ui_DatabaseSettingsWidgetGeneral.h
            ├── ui_DatabaseSettingsWidget.h
            ├── ui_DetailsWidget.h
            ├── ui_EditEntryWidgetAdvanced.h
            ├── ui_EditEntryWidgetAutoType.h
            ├── ui_EditEntryWidgetHistory.h
            ├── ui_EditEntryWidgetMain.h
            ├── ui_EditEntryWidgetSSHAgent.h
            ├── ui_EditGroupWidgetMain.h
            ├── ui_EditWidget.h
            ├── ui_EditWidgetIcons.h
            ├── ui_EditWidgetProperties.h
            ├── ui_EntryAttachmentsWidget.h
            ├── ui_MainWindow.h
            ├── ui_PasswordGeneratorWidget.h
            ├── ui_SearchWidget.h
            ├── ui_SettingsWidgetGeneral.h
            ├── ui_SettingsWidgetSecurity.h
            ├── ui_SetupTotpDialog.h
            ├── ui_TotpDialog.h
            └── ui_WelcomeWidget.h

After a couple hours trying to make it work, I've noticed something weird. The red underline will go away (and the code navigation will work too) only if I build the project in Debug mode (i.e. it'll only pick the file from the cmake-build-debug). If I clean the debug build and use the release build, there's no way I can get CLion to pick the file from cmake-build-release. Same applies for cmake-build-relwithdebinfo.

The code compiles and runs just fine, meaning that the CMake configuration is correct.

Just manually reload cmake project after build. It works fine for me.

You can solve this problem by changing Clion environment under Build, Execution, Deployment > Toolchains to use compilers installed with Qt instead. For MinGW 64bit you'll find it under C:\Qt\Qt5.x.x\Tools\mingwxxx_64.

this answer https://stackoverflow.com/a/31293158/192798 helped me find the solution for my case. i also had the same issue for you where it used to work and then suddenly couldn't find the header file. for me, i used target_include_directories so i had to tell clion to choose the configuration corresponding to the target. (i was choosing one of the target's dependents.) then i build, then i can switch to any configuration.

for your case, after switching the configuration, you may need to build to get clion to pick up the file.
