CMake Error at CatchTests/CMakeLists.txt:14 (add_executable):
Cannot find source file:

CMake Generate step failed. Build files cannot be regenerated correctly

In latest main branch, I build on ubuntu-latest.It's just a case issue in the file name.
I also found many same problems in source files,head file take the wrong name.
Does windows have same problems?I can't compose this project.

Since I mainly use this on Windows(due to work), building on Linux hasn't been applied. I experimented on Linux once by completely disabling CatchTests in the CmakeLists.txt and then building it, you might get a better result this way. But Windows build is stable. Here is the link to yaml file on how Github Actions was done on Windows VM c-cpp.yml

Then I build it on linux with ctest disabled,but there have the similar head file case issues.I think this is related to the Linux compiler being case-sensitive with header files. I suggest standardizing the capitalization of header file names.
I will try to make this project support Linux, but I don't have time right now. Thank you for your contribution.
