How to rebuild c++ extension when using pyproject.toml

I have a few C++ extensions for a python library.

Previously, this library was shipped using setup.py and one could recompile via python setup.py build_ext --inplace if only the C++ files changed.

Since I had to change the build system to manage more complex dependencies, I switched over to pyproject.toml + scicit-build-core + CMake.

Unfortunately I cannot find any way of how to recompile the changed files in this new setup. At the moment I have to always call pip install . which goes through the whole python dependency management and compiles everything.

TLDR: What is the equivalent of make in this setup?

pip install --no-deps . gets rid of the python dependencies part, but it still recompiles all cpp files, even if they were not changed.

Option 1:

1. Create a build directory:
   mkdir -p build && cd build

2. Configure CMake once:

   cmake .. -DCMAKE_BUILD_TYPE=Debug

3. Build incrementally:

   cmake --build . --config Debug -j$(nproc)

4. Install locally (without reinstalling via pip):

   cmake --install . --prefix ../install

   Option 2:
   1. Install the CLI tool:
   pip install scikit-build-core[pyproject]
   2. Run an in-place build:
   python -m scikit_build_core.build --wheel --no-isolation
