Windows path length message is wrong.

[Timmmm]

I get this error:

  Error: Too long output directory: `\\?\D:\lockfw\target\riscv32imac-esp-espidf\release\build\esp-idf-sys-eac617bcbe734de9\out`. Shorten your project path down to no more than 10 characters (or use WSL2 and its native Linux filesystem). Note that tricks like Windows `subst` do NOT work!       

However as you can see my project path is D:\lockfw which is only 9 characters. But if you search for that error, it's from here:

    #[cfg(windows)]
    {
        if out_dir.len() > 88 {
            report(format!("Too long output directory: `{out_dir}`. Shorten your project path down to no more than 10 characters (or use WSL2 and its native Linux filesystem). Note that tricks like Windows `subst` do NOT work!"))?;
        }
    }

That's checking the length of \\?\D:\lockfw\target\riscv32imac-esp-espidf\release\build\esp-idf-sys-eac617bcbe734de9\out which is 90 characters. So my path has to actually be a maximum of 8 characters!? Three of which are D:\ so I get 5 characters??

That's practically unusable. I think at that point there has to be a better solution. What part of the compilation process needs these really long paths?

I did also try ESP_IDF_PATH_ISSUES=warn and it compiled successfully (as far as I can tell). So maybe the check is just wrong?
