Hi.
I cannot build opencv4 package under Debian 12 (on older Debian it works). I've
prepared minimum scenario to reproduce:

Download and unpack: `buildroot-2024.02.tar.gz`

Go to BR dir.

make freescale_imx8mmevk_defconfig
./utils/config --enable CCACHE
./utils/config --enable TOOLCHAIN_EXTERNAL
./utils/config --enable PACKAGE_OPENCV4
./utils/config --enable PACKAGE_OPENCV4_WITH_TBB
make olddefconfig
make opencv4

...

It looks like sth is messed in opencv4 cmake files.
