If you require this for VS only, the

set(CMAKE_USE_RELATIVE_PATHS ON)

trick mentioned on this thread may work, as Windows in general and the
LLVM project files in particular doesn't use absolute paths as much as
the POSIX platforms do (for RPATH, executing external commands,
etc). Please give it a try.

If there are absolute paths remaining on the VS project files, they may
be the result of generating them in the LLVM CMake files with the
`abspath' operator, or could come from CMake built-in variables that
default to the absolute form. We could see if those could be replaced by
relative paths.
