Error while building colmap with vcpkg, any alternative with prebuilt colmap?

I tried installing colmap with vcpkg as suggested in the documentation vcpkg install colmap[cuda]:x64-windows

I faced an error which is described in the following issue: https://github.com/microsoft/vcpkg/issues/27956

So meanwhile, I already have a prebuilt colmap installed, and I have the COLMAP.bat in my path. Yet when I’m running ns-process-data it says that COLMAP is not found.

Do you have any info if there is a workaround? Especially if I can avoid having to recompile all I need myself.

OS: Windows 10 nerfstudio: installed with pip in a conda environment.

I saw that in the google collab setup so I tried just before leaving work and the colmap I got seemed to not be working (returned immediately without running anything). I’ll dig deeper in the coming days, but not tomorrow as I’ve other things on my plate right now and was exploring nerfstudio while waiting on other things at work. Anyway, I’ll definitely persevere in the coming days / weeks and report here solutions or issues.

I’m not sure what I did wrong the first time around when trying to use colmap with the prebuilt archive. I retested everything and now it seems to be working. So as a summary for how to get colmap working with nerfstudio on windows:

• OK: extract prebuilt colmap from latest release and add to the PATH the directory containing the COLMAP.bat file
• NOT ok: install via vcpkg. There is a visual studio 2022 bug.
• NOT ok: install via conda. The executable returns immediately.

After trying many things, the conda behavior is the same as if trying to execute the bin/colmap.exe file inside the colmap archive. So maybe I’m wrong, but it could be a hint that the conda install places the bin/colmap.exe in our path instead of the bat file.
