[Buildroot] [PATCH] gst1-imx: make kernel dependency optional

Baruch Siach baruch at tkos.co.il
Mon Apr 18 10:05:19 UTC 2016


The i.MX specific kernel headers are not a hard dependency. Quoting README.md:

  Without [--kernel-headers], the [ipu.h] header is not found, and elements
  using the IPU will not be built.
