title: dev packages not getting included in Yocto SDK
body: <p>We are generating Yocto SDK using the following command: <code>bitbake -c populate_sdk &lt;image-name&gt;</code></p>
  <p>Yocto Branch : Dunfell</p>
  <p>We don't see header files getting included in the SDK, for example we have libmodbus part of IMAGE_INSTALL, we don't see modbus.h file in SDK which is present in libmodbus-dev package</p>
