set_configvar() for a directory path is not correct for backslashes in Windows.

[Extra-Creativity]

set_configvar("DIR", "$(projectdir)") with add_configfiles will generate a macro in config.h, but this macro will have only one backslash in C/C++. To prevent escape characters, shouldn't it be a raw string or have two backslashes?

Or is there any way that I can pass the directory macro to my C/C++ program?

set_configvar("DIR", os.projectdir():gsub("\\", "/"))

It seems that gsub returns a table [replacedStr, matchTimes], so maybe it needs some simple process. I've changed it in my file :).

Thanks for your tolerance to my ignorance on XMake and lua (XD. I will forge ahead on studying it.

use () to wrap it, set_configvar("DIR", (os.projectdir():gsub("\\", "/")))
