Build icinga2 from sources for systemd systems

Hello, I’ve got a little problem with build the Icinga2 from sources.
I’m using this doc as an example -> https://icinga.com/docs/icinga2/latest/doc/21-development/#building-icinga-2-example

The problem is when I’m using USE_SYSTEMD=On in my commands
cmake -DCMAKE_BUILD_TYPE=Debug
-DICINGA2_UNITY_BUILD=OFF
-DUSE_SYSTEMD=ON
-DBoost_NO_BOOST_CMAKE=TRUE
-DBoost_NO_SYSTEM_PATHS=TRUE
-DBOOST_LIBRARYDIR=/usr/lib64/boost169
-DBOOST_INCLUDEDIR=/usr/include/boost169
-DBoost_ADDITIONAL_VERSIONS=‘1.69;1.69.0’
-DCMAKE_INSTALL_PREFIX=/opt/icinga2…;
make -j2;
make -j2 install

cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo
-DICINGA2_WITH_TESTS=ON
-DUSE_SYSTEMD=ON
-DICINGA2_UNITY_BUILD=ON
-DBoost_NO_BOOST_CMAKE=TRUE
-DBoost_NO_SYSTEM_PATHS=TRUE
-DBOOST_LIBRARYDIR=/usr/lib64/boost169
-DBOOST_INCLUDEDIR=/usr/include/boost169
-DBoost_ADDITIONAL_VERSIONS=‘1.69;1.69.0’
-DCMAKE_INSTALL_PREFIX=/opt/icinga2…;
make -j2;
make -j2 install

everything is ok after build process, icinga is working but the systemd unit file doesn’t create. I’ve tried different ways to fix this but can’t solve the problem.
Could you help me with this problem?
