Determine build tools & args based on yocto sdk env setup script
Browse files Browse the repository at this point in the history 
Previously, the yocto SDK for i.MX 8M devices of version 5.10-hardknott
is the only one to be supported, the build tools and arguments are
hard-coded.

Now to support different versions of SDKs for different devices, read
from the SDK env setup script to get info about build tools and
arguments.

env PKG_CONFIG_PATH is removed because with the gn arg sysroot correctly
set the package config path info can be retrieved automatically in the
build system.

For debug build, to eliminate warnings, optimize_debug is set.

With this patch applied, example commands to build the binaries are:

  export IMX_SDK_ROOT=/opt/fsl-imx-xwayland/5.15-kirkstone
  source scripts/activate.sh

  ./scripts/build/build_examples.py --target imx-all-clusters-app build
  ./scripts/build/build_examples.py --target \
          imx-all-clusters-app-release build

  ./scripts/examples/imxlinux_example.sh \
          examples/all-clusters-app/linux \
	  examples/all-clusters-app/linux/out/aarch64

  ./scripts/examples/imxlinux_example.sh \
          examples/all-clusters-app/linux \
	  examples/all-clusters-app/linux/out/aarch64 debug
