FindSystemd
-------
Finds the Systemd library.
Imported Targets
^^^^^^^^^^^^^^^^
This module provides the following imported targets, if found:
``Systemd::libsystemd``
The Systemd library
Result Variables
^^^^^^^^^^^^^^^^
This will define the following variables:
``Systemd_FOUND``
True if the system has the Systemd library.
#]=======================================================================]
# Use pkg-config if available
find_package(PkgConfig QUIET)
pkg_check_modules(PC_SYSTEMD QUIET libsystemd)
# Find the headers and library
find_path(
Systemd_INCLUDE_DIR
NAMES "systemd/sd-daemon.h"
HINTS "${PC_SYSTEMD_INCLUDEDIR}")
find_library(
Systemd_LIBRARY
NAMES "systemd"
HINTS "${PC_SYSTEMD_LIBDIR}")
# Extract additional flags if pkg-config is available
if(PC_SYSTEMD_FOUND)

"_systemd")
endif()
# Forward the result to CMake
