...to remove the temptation to put everything in one file with the same
name as the module. This doesn't do anything for overlays that /already/
have everything in one file with the same name as the module, except for
a few easy cases; we can unpack the rest later.
os/activity.h or os/log.h. Update cmake files again, hardcoding a Darwin
dependency. The script does not notice that Foundation depends on
CoreGraphics, so add that manually.
Also found that MapKit is supported on WATCHOS but we didn't have dependencies
for that.
Favor one line per supported SDK instead of catch-all dependency lines.
Distinguish from SDKs which have no dependencies vs SDKs which are
unsupported on a particular platform by printing `unsupported` to the
console and remove the line in the cmake file because it should
not exist anyway.
This full cleanup was not done before because of circularity detected by the
util, which has since been fixed.
Support directories with spaces.
added the build breaks. There's already a tool to get proper
dependencies, `utils/find-overlay-dependencies.sh`, so this patch
allows that tool to update the `CMakeLists.txt` files in-place.
Also it adds a line to the `CMakeLists.txt` files for each SDK so that the tool works.
