I don't know if this problem is related to this project, or if the problem is related to CMake or another tool. Anyway, I wrote here, because I am taking this project, and when I add ENABLE_COVERAGE, the coverage, for example, Experimental build target failed. If ENABLE_COVERAGE is off, the coverage step is skipped. This target is related and documented in CTest.

For easier repeating the problem and knowing what I am talking about, I am trying also in FTXUI template from cpp-best-practices, because I know @lefticus is a contributor of Ftxui and project_options and this will be the perfect project for repeating the problem. In this project, I just add ENABLE_COVERAGE in dynamic_project_options and run preset GCC Debug and target Experimental. Is the same problem if I am using different preset configurations. It is also the same if I change from dynamic_project_options to project_options. I am using VSCode and docker all the same setup is defined in the project.

The output of unixlike-clang-debug - Experimental in the project ftxui_template

The problem is in /workspaces/ftxui_template-main/out/build/unixlike-clang-debug/src/CMakeFiles/intro.dir exist .gcda, .gcno and .o file.

So my question is if I am doing something wrong? I'm new in CMake preset and with this project. Also, it seems like something is not well set for CTest when the coverage is enabled. I have the same problem in my project as in Ftxui.
Also, any help on how to investigate, test, and fix the problem will be very pleasant. Thank you for all your tips and investigations.
