Thanks very much!  As mentioned in the other message, I would prefer to 
have a single script so here is what I came up with.

#!/bin/sh -e
#
# Helper script for the build process to apply entitlements

copy=:
if [ "$1" = --install ]; then
   shift
   copy=false
   cd "$MESON_INSTALL_DESTDIR_PREFIX"
fi

SRC="$1"
DST="$2"
ENTITLEMENT="$3"

if $copy; then
   trap 'rm "$DST.tmp"' exit
   cp -af "$SRC" "$DST.tmp"
   SRC="$DST.tmp"
fi

codesign --entitlements "$ENTITLEMENT" --force -s - "$SRC"
mv -f "$SRC" "$DST"
trap '' exit


I'll include this in the next pull request, since I was able to test it 
with Cirrus CI.

Thanks,

Paolo
