[BUG] preview-build generating excessive sub-directories recursively

[dl-davi]

I reported this error once, and it happened again:

[LVGL] CMake Error at CMakeLists.txt:1 (cmake_minimum_required):
  Maximum recursion depth of 1000 exceeded

Builded my project normally using CTRL+SHIFT+B, .c files were generated normally, but at the end of the build, while generating the contents of /preview-build, the build process broke and created a thousand of sub-directories inside /preview-build/project. The directory always has /CMakeFiles and /project, and inside this /project the recursion happens again.

@dl-davi, can you provide an example project, where it occurs? Or something that we can test on?

[JohnGoewert]

I don't have a project to test this with, but have encountered the same issue several times. Next time I get it, I'll see if I can grab a log.

My temp fix is to delete the /preview-build folder after it makes /preview-build/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/project/...

@laszlobalint Right now I don't have a project that I can share, but I will try to recreate the issue in another project. If it happens again I will share here.

@JohnGoewert Same here, usually the next build runs smoothly. But there were times when even deleting the subfolders didn't solved, just by restarting the application.
