Hi Mani,

The problem is that ar the executable is not installed. The immediate
solution is to add add a build dependency on binutils.

However you appear to be calling autotools from insde cmake. That's going
to be fragile and is not recommended as it's not going to behave well in
both the devel and install workspaces without quite a few hacks. (Such as
forcing a rebuild every build) It's probably better to package the
different package separately or quickly rewrite the build for the package
in cmake.  Note your current cmake does not install any of the SDK so it
won't work when someone tries to use your installed packages if it needs
either a library or header from the sdk.
