You may also want to set USE_BUNDLED_JSONCPP here.

This command actually build the kernel module, so should be in a _BUILD_HOOK ;-)

The weird thing here is that you manually build/install the kernel
module, whereas AFAICS it should be automatically done by the
build-system (the driver directory is always scan in the Buildroot
context (see [1]), and BUILD_DRIVER is ON by default ([2])).
I suggest to disable BUILD_DRIVER in the conf. options.
