Describe the bug
When I update all installed packages, I always get an error message that the path to the compiler information supposedly does not exist. The path it attempts to open starts with C;/ (semi-colon) instead of C:/ (colon) and therefore results in an error.

Environment

• OS: Windows 11
• Compiler: MSVC 19.42.34435.0

To Reproduce
Steps to reproduce the behavior:

1. Go to the folder of your VCPKG installation
2. Open Terminal and run .\vcpkg.exe upgrade --no-dry-run

Expected behavior
VCPKG is expected to upgrade all installed packages

Failure logs
C:\vcpkg\buildtrees\detect_compiler\stdout-x64-windows.log

CMake Error at C:/vcpkg/scripts/ports.cmake:143 (message):
  Cannot find port:

    Directory does not exist: C;/vcpkg/scripts/detect_compiler
