Unless 3rd party extensions vendor php-src and/or do something extra
besides what they are instructed to do in the docs (phpize and all the
fun stuff), you can perfectly retain the external functionality for
existing consumers of php-src with the right amount of build system
engineering, which is what I'm offering here.

You could choose this to be maintained for as long as necessary with a
clear migration guide documenting what needs to change, which shouldn't
be a lengthy document if we assume the happy path mentioned above. I am
always available to dispense help for 3rd parties regarding CMake if
necessary.

Regarding that last bit, would it make sense to create a new mailing
list (php.cmake?) where questions could be posted, answered and nicely
organized?
