Defines version of systemd to be downloaded, built and integrated into sdbus-c++. Default value: `242`.
* `LIBSYSTEMD_EXTRA_CONFIG_OPTS` [string]
Additional options to be passed as-is to the libsystemd build system (meson for systemd v242) in its configure step. Can be used for passing e.g. toolchain file path in case of cross builds. Default value: empty.
* `CMAKE_BUILD_TYPE` [string]
This is a CMake-builtin option. Set to `Release` to build sdbus-c++ for production use. Set to `Debug` if you want to help further develop (and debug) the library :)
