# NOTE **This is a hack for lsp only and is not needed for compilation to succeed**
# Should probably be commented out for serious compilation.
# clangs lsp will not find the headers for zlib and gtest. The linking below
# is not enough to add include info on the headers to the compile commands.
# It is possible this has something to do with nix. However nix stores the
# paths to these includes in the below environment variable and they can be
# added to the compile commands. I should probably find a different way, but I
# have been messing with this for several hours and need to work on my code
# not fiddle with tools.
