我在buildroot中添加scikit-learn包，但它在构建步骤中需要scipy依赖性，因此我在python-scipy.mk中添加host-python-scipy，如下所示：

HOST_PYTHON_SCIPY_DEPENDENCIES += \
        host-python-numpy \
        host-python-pythran \
        zlib \
        lapack \
        python-numpy \
        python-pybind

然后我rebuild scikit-learn，但它给出了另一个错误No BLAS/LAPACK libraries found：

To build Scipy from sources, BLAS & LAPACK libraries need to be installed.

Buildroot有MKL库吗？我如何添加它？
我循着这个建议得到了回答，但我碰到了另一个问题：

Traceback (most recent call last):

    setup_package()

make:***[package/pkg-generic.mk:293: /home/xxx/buildroot/output/build/python-scikit-learn-1.1.2/.stamp_built] Error 1

pkg-generic是做什么用的？有没有办法在不避免测试执行的情况下解决这个问题？我能得到一些帮助吗？
