"This file does not belong to any project target..."

Hi! Is the project loaded correctly? I mean, are there any errors in the CMake tool window? Do you see the "This file does not..." error for both "main.cu" and "lib.cuh"?

Thanks for your help!

> Is the project loaded correctly?

I am not sure how to check, but it runs fine using Clion's native Cmake build & run

> I mean, are there any errors in the CMake tool window?

no errors when I build, if that is what you mean by "errors on CMake tool window"

yes

Please do Tools | CMake | Reset Cache and Reload Project and copy the entire output from the CMake tool window (View | Tool Windows | CMake) here.

Here is the output:

It's my first time using CMake, so could you help me troubleshoot? 

Thanks so much!

I was able to fix the above Cmake error. However, in the "Debug" Cmake console, I get the error statemet:

```

Cannot generate 'Debug' into /home/minds/isaac/tf_bilinear_upsample
CMakeCache.txt is found in the project dir, only in-source generation will be performed.

[Failed to reload]

```

and all the files still display the error message "This file does not belong to any project target..."

ping!

Is /home/minds/isaac/tf_bilinear_upsample your project folder? Have you changed the Generation path option in File | Settings | Build, Execution, Deployment | CMake? CLion should generate CMake files in the cmake-build-debug subfolder by default.

/home/minds/isaac/tf_bilinear_upsample this is a remote path mapped to my local project folder, not my local project folder.

Generation path for both default and debug are set as: /home/minds/isaac/tf_bilinear_upsample and I have not touched this.

A remote path? Do you use the full remote mode?

Please describe how your development process is organized, I don't understand it.

I got this when I copied a file from another project into a new project I was working on.  When I tried to make changes I got this error with possible actions like "I want to edit this file anyway..."  It would seem useful to offer the additional option "Add this file to my project" -- of course if it's a symlink to the other projects file then that's not a viable thing to do without some sort of "clone/copy" done ahead of assigning ownership to the project, but I think that could be managed.
