Python2 port is missing git information and uses the wrong platform toolset

[jbayardo]

When installing the python2 port, a few calls to git are made within the build:

git name-rev --name-only HEAD
git rev-parse --short HEAD
git describe --all --always --dirty

Since the port is downloaded as a zip file without additional git information (concretely, the .git directory), git will start traversing directories up in the tree looking for .git. In an environment with restricted access, this will hit vcpkg's .git and attempt to write the index.lock, leading to a restricted write.

It also attempts to build using PLATFORM_TOOLSET set to the default of VCPKG_PLATFORM_TOOLSET, which could be v141. The officially supported value is v140.

VCPKG determines the setting of VCPKG_PLATFORM_TOOLSET from the environment see vcpkg_platform_toolset

I will take a look at the git issue.
