CMake Warning at source_subfolder/CMakeLists.txt:69 (find_package):
  By not providing "FindSystemd.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Systemd", but
  CMake did not find one.

  Could not find a package configuration file provided by "Systemd"
  (requested version 209) with any of the following names:

    SystemdConfig.cmake
    systemd-config.cmake

  Add the installation prefix of "Systemd" to CMAKE_PREFIX_PATH or set
  "Systemd_DIR" to a directory containing one of the above files.  If
  "Systemd" provides a separate development package or SDK, be sure it has
  been installed.


CMake Warning:
  Manually-specified variables were not used by the project:
