Drops files if the directory in compile_commands has different cases than the one in CWD (WSL)

[Gogo64pro]

In wsl you can cd into a directory without the correct case so
cd /mnt/c/Folder1
is the same as
cd /mnt/c/foLdeR1
if the CWD is the same directory but has different case it won't add any of the files in the final .scip because it thinks they are part of a different directory
