how to used cmake link the pthread and CURSES

Question

I don't know how to link the curses. h and pthread. h with *.c and *.h in clion CMake. no matter how I change it, it all wrong with "undefined reference to ". I think is make by curses head file. I tried many different methods to make the cmakelist.txt, but it was always wrong. I don't know what always wrong. of course I don't know what correct method should be used.

cmake error output:

my CMake file :

cmake_minimum_required(VERSION 3.17)
project(as3 C)

set(CMAKE_C_STANDARD 99)
find_package(Curses REQUIRED)
include_directories(${CURSES_INCLUDE_DIR})
add_executable(as3 centipede.c centipede.h console.c console.h main.c player.c player.h threadwrappers.c threadwrappers.h)
target_link_libraries(as3 ${CURSES_LIBRARIES})
set_target_properties(as3 PROPERTIES LINK_LIBRARIES -lpthread)

What happens if you do `set(CURSES_NEED_NCURSES TRUE)` before `find_package(Curses REQUIRED)`? Regarding pthread, please see [this](https://stackoverflow.com/questions/1620918/cmake-and-libpthread) question (try using `target_link_libraries(as3 Threads::Threads)` — icebp, Mar 12 '21 at 07:52
By setting `LINK_LIBRARIES` property you have cleared the effect of `target_link_libraries(as3 ${CURSES_LIBRARIES})`. Do not set this property, use `target_link_libraries` instead. — Tsyvarev, Mar 12 '21 at 07:56
