[bug]: Malformed INCLUDE/LIB Paths Due to Semicolon Handling. #18978
Description
Describe the bug
Details : Conan version 2.16.1, windows 11, MSVC v170, microsoft visual studio 2022.
This is not a bug in Conan itself, but rather a misbehavior in how environment variables are handled when Conan sets them up for Visual Studio builds.
When Conan accumulates import paths (e.g., for INCLUDE, LIB, etc.), the stacking of these paths includes semicolons (;) as part of the actual path value, rather than using them strictly as separators. This leads to malformed environment variables.
So instead of looking like this
It should look like this.
Another option is that conan imports could be listed as one.
This subtle issue did not cause any problem, but I had trouble finding one of my imports that I thought was missing.
How to reproduce it
Any Windows os with multiple imports using msbuilddeps.py should have this issue.
