How does vcpkg find Visual Studio?

[thxkiwi]

I have a vcpkg_root that is integrated with Visual Studio 2019 installed on the system drive (C:).

I'd like to have another vcpkg_root that is integrated with a different installation of the build tools located on D:

How can I make vcpkg find and use a specific location of the toolchain?

You are looking for VCPKG_VISUAL_STUDIO_PATH?

I should've found this myself.

Thank you.

Seems like I need a little more help here...

What exactly is vcpkg looking for? Are there vcpkg logs somewhere? I know the buildtrees have logs for each package/port but I'm not sure where to look for logs of vcpkg itself.

bump

I'm happy to dig through a vcpkg install I'm just not sure where to begin to determine why setting VCPKG_VISUAL_STUDIO_PATH is not able to find a valid install. This install is definitely usable for building any C/C++ MSBUILD project.

Can anyone help me understand why vcpkg insists this is not a usable instance?

[thxkiwi]

@autoantwort any ideas why vcpkg wouldn't find a usable instance with the above? [thanks for understanding my tagging you here. Haven't got a lot of traction on this one. Grateful for any help you can offer.]

[autoantwort]

No, sorry
