value on L73 is set to the absolute path to lld-link
compiler on line L96 is set to only lld-link

failing command is:
['lld-link', '/logo', '--version', '-nologo', '-DWIN32', '-D_WINDOWS', '-FC', '-arch:AVX', '-clang:-fasm', '-clang:-fopenmp-simd', '-utf-8', '-Od', '-Ob0', '-GS', '-RTC1', '-MDd', '-Zi', '-IE:/src/AllProjects/build/vcpkg_installed/x64-windows-llvm/include']
which returns some warnings e.g.:
lld-link: warning: ignoring unknown argument '-DWIN32' but also LLD 13.0.0

[Neumann-A]

That being said. The issue here is that a compiler = value line seems to be missing or meson is assuming that lld-link is one path.

Doesn't seem to be a regression in 0.60.2? Not sure why the title implies it is.
