CMake 链接 OpenSSL 静态库

2022-08-23 22:24:21 3054

示例CMakeLists.txt如下

cmake_minimum_required(VERSION 3.5)

project(test CXX)

set(CMAKE_CXX_STANDARD 11)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wno-unused-function")

set(SYSTEM_LIBS stdc++ pthread)

# 静态编译
set(CMAKE_EXE_LINKER_FLAGS "-static")

add_executable(${PROJECT_NAME} main.cc)

find_library(SSL_LIB libssl.a REQUIRED)
find_library(CRYPTO_LIB libcrypto.a REQUIRED)


target_link_libraries(${PROJECT_NAME}
        ${SSL_LIB}
        ${CRYPTO_LIB}
        ${CMAKE_DL_LIBS}
        ${SYSTEM_LIBS})

若链接的其他静态库也链接了OpenSSL, 则要注意链接顺序

• c++
• openssl
• cmake
