layoutex is enabled by default by configure iff hb-le-icu is installed. It would probably be better to require explicit opt-in if layoutex is desired… actually, layoutex would be better as a separate component (if it is even desired due to its complex build process.)
will just change the default
I increased the priority to “medium” because I have seen people getting tripped up by having the prerequisites installed, getting layoutex configured by default, and having build problems with it even though they don’t care to build and use it.
time to set the defaults: 20s
time to get HB actually compiling and make sure it works: ≥20s
