To help understand the command and associated errors, I edited your text to use both backquotes \[1\] and `^` to split windows command.

Could you indicate which version of Slicer you are attempt to build ?

If you have shared libraries in a folder that is in your system PATH environment variable then anything can happen, including build and/or runtime failure of any application. Therefore, the system PATH environment variable should be kept clean - there are several alternative ways to make utilities conveniently available, for example using [App Paths registry key](https://learn.microsoft.com/en-gb/windows/win32/shell/app-registration).

Confusing entries in the system PATH might have corrupted your build. So after removing all non-system paths from your PATH I would recommend to delete the entire Slicer build folder and restart the build from scratch. I would also recommend putting your build commands into a .bat file to allow (re)building Slicer anytime by a single click.
