动态链接配置

使用系统自带的openssl动态库

find_package(OpenSSL REQUIRED)
if(OPENSSL_FOUND)
  include_directories(${OPENSSL_INCLUDE_DIRS})
  message(STATUS "OpenSSL Found!")
endif()


target_link_libraries(target_program ${CURL_LIBRARIES})
target_link_libraries(target_program OpenSSL::Crypto OpenSSL::SSL)

如果不想使用系统自带的openssl ，可以指定版本的openssl路径

给cmake添加下列变量：

-DOPENSSL_INCLUDE_DIR：指向 openssl-1.0 的 include 目录
-DOPENSSL_SSL_LIBRARIES：指向 openssl-1.0 的 lib 目录中的 libssl.so
-DOPENSSL_CRYPTO_LIBRARIES：指向 openssl-1.0 的 lib 目录中的 libcrypto.so

// add_definitions(-DOPENSSL_INCLUDE_DIR)

静态链接配置

添加以下的变量定义

set(OPENSSL_ROOT_DIR /home/public/openssl) 
set(OPENSSL_USE_STATIC_LIBS TRUE)

不使用cmake编译

./configure  --prefix=/home/webrtc/thirdparty/libsrtp-2.3.0/release  --enable-openssl  --with-openssl-dir=/home/webrtc/thirdparty/lib/openssl
make
make install

静态链接zlib

find_package(ZLIB REQUIRED)
if(ZLIB_FOUND)
  message(STATUS "Zlib Found!")
  include_directories(${ZLIB_INCLUDE_DIR})
endif()

target_link_libraries(target_program ${ZLIB_LIBRARIES})
