   I would be useful to have instructions on which files to remove to fully undo a make install.

   Looking at the install log, something like this:

   0sudo rm -rf /usr/local/lib/libmultiprocess.a \
   1/usr/local/include/mp \
   2/usr/local/bin/mpgen \
   3/usr/local/include/mp \
   4/usr/local/include/mpgen.mk \
   5/usr/local/lib/pkgconfig/libmultiprocess.pc \
   6/usr/local/lib/cmake/Libmultiprocess
   

   That’s a lot of files, so a make uninstall would be easier to use.

   It looks like a reasonable way to do this is:

   0xargs rm -v < build/install_manifest.txt
   

   as described https://stackoverflow.com/questions/41471620/cmake-support-make-uninstall

   It’d be probably a good idea to add that command to the documentation in https://github.com/bitcoin-core/libmultiprocess/blob/master/doc/install.md

   It would also be possible to add a more portable make uninstall target as described https://gitlab.kitware.com/cmake/community/-/wikis/FAQ#can-i-do-make-uninstall-with-cmake if that is not overkill.

   Would welcome opinions about this, or PRs implementing any solution.
