boost-build bootstrapping failing with "The system cannot find the path specified."

Running the build.ps1 as recommended by the instructions results in the following error:

GitHub Continuous Integration builds are fine for 2024.01.05 and current "head" as well.

We suspect a long directory path or a dot in the directory name because of the following notice in vcpkg documentation https://github.com/microsoft/vcpkg?tab=readme-ov-file#quick-start-windows:

"First, download and bootstrap vcpkg itself; it can be installed anywhere, but generally we recommend using vcpkg as a submodule so the consuming repo can stay self-contained. Alternatively, vcpkg can be installed globally; we recommend somewhere like C:\src\vcpkg or C:\dev\vcpkg, since otherwise you may run into path issues for some port build systems."

Follow up ideas:

• simpler path can be checked on original machine
• more complicated path can be checked on CI machines
