Recompiling and Problems with cmake - cmake

Question

first sry for my gramma or my faults, i'm german but i'll try my best ;)
OK, now straight to the problem:
I'm trying to recompile my source but everytime, i got some faults.
So becouse my knowledge of cmake isn't so far, i hope to find help from you.
The project is about an azerothcore privat wow server and it's first to add thoes modules (CMakeList.txt's below) and to update the core itself.
Everytime, while trying "make -j 4; make install" the latest fail the console shows is
CMake Error at CMakeLists.txt:5 (CU_SET_PATH):
Unknown CMake command "CU_SET_PATH".
-- Configuring incomplete, errors occurred!
See also "/home/wajmanor/azerothcore/build/CMakeFiles/CMakeOutput.log".
Makefile:132: recipe for target 'cmake_check_build_system' failed
make: *** [cmake_check_build_system] Error 1
Thoses helps i found with google everytime want to see the log-file, and that's why i attached it already ;):
CMakeOutput.log
For the Advice (thx to Tsyvarev ), i add the both CMakeList.txt's that could couse the problem:
Mod Nr. 1
cmake_minimum_required(VERSION 3.10)
AC_ADD_SCRIPT("${CMAKE_CURRENT_LIST_DIR}/src/WorldChat.cpp")
AC_ADD_SCRIPT_LOADER("WorldChat" "${CMAKE_CURRENT_LIST_DIR}/src/loader.h")
AC_ADD_CONFIG_FILE("${CMAKE_CURRENT_LIST_DIR}/conf/WorldChat.conf.dist")
Mod Nr. 2
project(GuildHouse)
cmake_minimum_required(VERSION 3.16)
CU_SET_PATH("CMAKE_guildmaster_DIR" "${CMAKE_CURRENT_LIST_DIR}")
AC_ADD_SCRIPT("${CMAKE_CURRENT_LIST_DIR}/src/guildmaster.cpp")
AC_ADD_SCRIPT_LOADER("guildmaster" "${CMAKE_CURRENT_LIST_DIR}/src/loader.h")
Hope someone could help me....
