Near the end of building Polygeist, well the cmake command, I get

Libraries have been installed in:
   /mnt/d/LLVM/NewPolygeistDir/build/pluto/install/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the '-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the 'LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the 'LD_RUN_PATH' environment variable
     during linking
   - use the '-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to '/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

What is this install? I see candl in three palces in the repo

Can I build Polymer on its own and add it in or is there a workaround for this on WSL2?

Start at tools/polymer/CMakeLists.txt:28 and inspect the install command that reaches build/pluto/pluto/candl, where Makefile:555 reports the missing install target. Reproduce the configuration on WSL2 and compare CMakeOutput.log and CMakeError.log; done means Polymer configures without the candl install failure.
