Paths from config.toml do not get properly processed for the platform they run on

[hcldan]

Problem

setting a config.toml:

C_API_ROOT = { value = "target/lib/capi", force = false, relative = true }

results in something like this on windows: c:\\Users\\user\\git\\project\\target/lib/capi

Steps

For steps, see above.

Possible Solution(s)

Translate the path according to the platform processing the build, or give us a way to set the path based on the platform being built on or for.

If that is already possible, please make that information easier to access. Perhaps in https://doc.rust-lang.org/cargo/reference/config.html#configuration-format or the section about env.

Sorry, I'm not really clear, what is wrong with the path?

mixed / and \ characters

[ehuss]

Can you say more about what kind of problems that causes? Almost all the Windows APIs support both forward and backward slashes.

[hcldan]

I was having an issue (several actually) with some older windows compilers. I did end up ironing them out. After going back and removing the code I had for fixing up the path, it still works so I guess my issues were unrelated.

I haven't yet tried some older compilers, but hopefully that won't matter.
I'll re-open if I run into further issues with this.
