Yocto Add own Header and Lib file's to sdk - sdk

Question

i want to add .h and .lib files to a own created recipe to the sdk.
I use cmake to build my lib's, with the sdk i can build it.
My recipe name is served. (i want to add the served https://github.com/meltwater/served as a own recipe).
in my served_0.1.bb File i add following:
BBCLASSEXTEND = "native nativesdk"
RDEPENDS_${PN} += "nativesdk-served"
in the layer.conf i add:
TOOLCHAIN_TARGET_TASK_append = " served "
When i start to create my sdk with
bitbake core-image-base -c populate_sdk
ERROR: core-image-base-1.0-r0 do_populate_sdk: Could not invoke dnf.

Assuming that you have a recipe for served which compiles without errors.
The step to add served .h and lib files to sdk is to add below line to local.conf
TOOLCHAIN_TARGET_TASK_append = " served "
And then run command
bitbake core-image-base -c populate_sdk
The lines below in your served recipe are causing errors and are not needed for SDK generation. Please remove them and try building your image again.
BBCLASSEXTEND = "native nativesdk"
RDEPENDS_${PN} += "nativesdk-served"
