installing via "git+file" fails under Windows when url point to different drive-letter

Description

I clone an existing git-repo to Windows $TMP unsing src = tempfile.mkdtemp(prefix = 'thrift-src_') and tried to install this via PIP pip install f'thrift@git+file://{src}@@v0.18.1#subdirectory=lib/py'. This will fail, as long as my cwd is on a different drive than $TMP

The git command will not get the correct folder passed and tries to use the cloned one with the tag-name appended.

When I change to src = tempfile.mkdtemp(prefix = 'thrift-src_', dir = '\\source\\project'), the package gets installed without worries. The difference seems only the absence of specifying the drive-letter.

Expected behavior

Pip should be able the install via "git+file://" from any drive / any location

pip version

24.0

Python version

3.11.9

OS

Windows 10

How to Reproduce

change to project folder on different drive than C: (cd d:\test)
git clone https://github.com/apache/thrift C:\sven\AppData\Local\Temp\thrift
pip install thrift@git+file://C:\sven\AppData\Local\Temp\thrift@v0.18.1#subdirectory=lib/py'

Output

D:\source\project> python tests\automated\test-02_integration-test.py --build-dir build\x64-Debug --keep-env
