安装 libpcap

Question

Can someone explain me how to install libpcap? I downloaded libpcap-1.9.1 from official site (tcpdump). There are a lot of files and i cant understand what to do. i tried:

project(test)
set(CMAKE_CXX_STANDARD 14)
include_directories(libpcap-1.9.1)
list(APPEND CMAKE_MODULE_PATH "${CMAKE_CURRENT_LIST_DIR}/libpcap-1.9.1/cmake/Modules")
find_package(Packet REQUIRED)
add_executable(${PROJECT_NAME} main.cpp )
target_link_libraries(${PROJECT_NAME} ${PACKET_LIBRARY})

But it doesnt work

Answer 1

Just use add_subdirectory() with target_link_libraries() :

project(test)

set(CMAKE_CXX_STANDARD 14)

include_directories(libpcap-1.9.1)

add_subdirectory(libpcap-1.9.1)

add_executable(${PROJECT_NAME} main.cpp )

target_link_libraries(${PROJECT_NAME} PRIVATE pcap)
