The recipe specifies an additional package "${PN}-systemd" along with other systemd related variables and finally it instructs that the package should be built with "-DWITH_SYSTEMD=ON" being passed to cmake. So far so good. But, I extended this recipe to nativesdk because I need this library on it. When trying to build the corresponding nativesdk package, the build fails at the configuration step (i.e. "do_configure") claiming it cannot find the package systemd.

Make the systemd dependency for target only, e.g. DEPENDS_class-target += "systemd"
etc.

There may be relevant use cases to build some of systemd components or tools
to native or nativesdk targets too. In that case add BBCLASSEXTEND += "nativesdk" etc
in a bbappend to systemd.

Hope this helps,
