use network drive with X_VCPKG_ASSET_SOURCES without mapping it as a drive

[AbdulAbCellera]

I have a network-shared folder with FQDN myfs.hi.com/projs. I dont want to mount it, and I want to use it as the asset source. My issue is that I could not figure out the syntax for that.

mounted worked

set(ENV{X_VCPKG_ASSET_SOURCES} "x-azurl,file:///Z:/asset/,,readwrite")

regular dir worked

set(ENV{X_VCPKG_ASSET_SOURCES} "x-azurl,file:///$ENV{USERPROFILE}/asset/,,readwrite")

fails

set(ENV{X_VCPKG_ASSET_SOURCES} "x-azurl,file:///myfs.hi.com/projs/asset/,,readwrite")
set(ENV{X_VCPKG_ASSET_SOURCES} "x-azurl,file:///\\\\myfs.hi.com/projs/asset/,,readwrite")
set(ENV{X_VCPKG_ASSET_SOURCES} "x-azurl,file://///myfs.hi.com/projs/asset/,,readwrite")

I use the drive for binary caching and it works (notice the slashes)
set(VCPKG_DEFAULT_BINARY_CACHE "files,\\\\myfs.hi.com\projs\asset,readwrite")

I see this error

Please fill an issue instead of this.

I have a doubt that it is an issue. It is more of am I using it correctly? I know that it is only a shared network drive the does not support https and anything fancy.

If you still think I should file it as issue let me know.

Hmm, maybe we should improve the expression parser.

Hi, just had this problem simply because I didn't know how the file:// protocol works. To access network drives from root, the correct syntax is file://networkdrive/folder
