Breakpoints are not getting hit due to path case differences

[misterzed88]

I would like to mention a special border case that bit me when debugging a Linux target from a Windows host. Since the build sources were placed in a local Windows directory different from the original Linux build directory, I used the sourceMap option to map between them, as described in:
https://github.com/vadimcn/vscode-lldb/wiki/Breakpoints-are-not-getting-hit

The mapping was something like:
"/build/dir/on/linux": "X:/source/dir/on/windows"

Even though the paths were correct, LLDB failed to resolve the symbols to set breakpoints. The problem was due to the mapping containing the drive letter in upper case, while vscode-lldb used lower-case in its breakpoint path, leading to a mismatch in LLDB due to case-sensitive comparison.
By changing to lower-case drive letter in the sourceMap the problem disappeared.

There may be other scenarios leading to the same problem - with case differences - but I haven't investigated further.

It would be nice if something was mentioned about this in the Wiki page, to help other users avoid this problem.
