from .. import mesonlib
dependencies: Add a new class ExternalDependency This class now consolidates a lot of the logic that each external dependency was duplicating in its class definition. All external dependencies now set: * self.version * self.compile_args and self.link_args * self.is_found (if found) * self.sources * etc And the abstract ExternalDependency class defines the methods that will fetch those properties. Some classes still override that for various reasons, but those should also be migrated to properties as far as possible. Next step is to consolidate and standardize the way in which we call 'configuration binaries' such as sdl2-config, llvm-config, pkg-config, etc. Currently each class has to duplicate code involved with that even though the format is very similar. Currently only pkg-config supports multiple version requirements, and some classes don't even properly check the version requirement. That will also become easier now.

dependencies: Don't assume self.compiler is a C compiler All dependencies were using find_library, has_header, get_define, etc on self.compiler assuming that it's a compiler that outputs and consumes C-like libraries. This is not true for D (and in the future, for Rust) since although they can consume C libraries, they do not use the C ecosystem. For such purposes, we now have self.clib_compiler. Nothing uses self.compiler anymore as a result, and it has been removed.

Set is_found in AppleFrameworks constructor Set is_found in AppleFrameworks constructor, rather than overriding the found() method, as other superclass methods may access is_found.
