[gdal-dev] building python bindings after cmake compilation

[Saulteau Don]

I have gdal 3.5.0 built using the new cmake system.
/chroot/src/build <- cmake build directory
/chroot/src/gdal <- src directory
/chroot/src/gdal/swig/python

My cmake is ran from the /chroot directory:

> cmake -B build -S gdal \
>       -DCMAKE_BUILD_TYPE='None' \
>       -DCMAKE_INSTALL_PREFIX='/usr' \
>       -DBUILD_PYTHON_BINDINGS='OFF' \
>       -Wno-dev
> cmake --build build


Then to make the python bindings via swig:

> cd gdal/swig/python
> python setup.py build


When the `python setup.py build` is running it can't find gdal-config with
the following errors:

It's searching for it in ../../apps/gdal-config which is /chroot/gdal/apps
but could find it in /chroot/build/apps/gdal-config if it searched there
instead. Any way to point `python setup.py build` to look for gdal-config
in a custom path or the one that cmake built gdal in?
