Windows fix

[Squareys]

Hi @vincentdchan !

I found two places where absolute paths are checked by comparing the first char toPaths::PATH_DIV, which does not work for windows absolute paths (e.g. C:/windows or C:\\windows).

I use normalized paths already, but further it could be useful for others to convert \\ into / on windows.

Best,
Jonathan

PS: Do you know about std::filesystem? It might be a more platform independent way to implement these path utilities.

Great! Would you add some unit tests for the codes you committed in Path.h?

@Squareys I have been used std::filesystem's path class once, it's path will call system's API in path concatenation. Calling system's API is slow, it hurts the performance in benchmark. I try to do concatenation only in memory, so I wrote my own Path.
