# In certain unusual packaging layouts such as Nixpkgs, the Harfbuzz package
# is installed into two Nix store paths, "out" and "dev", where "out" contains
# libraries only (i.e. lib/libharfbuzz.so) and "dev" contains development
# files, i.e. include and lib/cmake. If CMake package files are installed to
# "out", Nixpkgs will move them to "dev", which breaks assumptions about
# our file paths. Since we need to figure out relative install paths here
# to make a relocatable package, we do need to know the final path of our
# CMake files to calculate the correct relative paths.
# Of course, this still defaults to $libdir/cmake if unset, which works for
# most packaging layouts.
