Extension

Buildcpp is not a closed build system, it provides an extensible interface called AbstractTarget. The Target provided by buildcpp is one of its subclasses. By inheriting AbstractTarget and implementing its abstract methods, you can achieve your own defined target logic.

target.py

...

class AbstractTarget(ABC):
    def __init__(self, name: str) -> None:
        ...

    @abstractmethod
    def to_cmake(self) -> str:
        pass

    def depend_on(self, *targets, allow_invaild=False):
        ...

    def rename(self, new_name: str):
        ...

...

The above is the definition of the abstract class AbstractTarget, which has an abstract method to_cmake used to customize the target logic. Buildcpp is similar to CMake in that it translates Python code into CMake, just like how CMake translates CMake scripts into Makefiles.
