Libcurl的简单使用

C++libcurl库的使用

Mac上配置libcurl库的环境变量，并在C++项目中通过CMakeLists.txt 文件引用

1.libcurl安装

brew install curl #如果是x86的cpu架构
arch -arm64 brew install curl #如果是arm的cpu架构

2.环境变量配置

.bash_profile或者.zshrc添加配置

# liburl
export CURL_HOME=/usr/local/opt/curl
export C_INCLUDE_PATH=$CURL_HOME/include
export CPLUS_INCLUDE_PATH=$CURL_HOME/include
export LIBRARY_PATH=$CURL_HOME/lib
export DYLD_LIBRARY_PATH=$CURL_HOME/lib

3.CMakeLists.txt引用libcurl库

find_path(CURL_INCLUDE_DIR curl/curl.h)
find_library(CURL_LIBRARY NAMES curl)
include_directories(${CURL_INCLUDE_DIR})

add_executable(my_program main.cpp)
target_link_libraries(my_program ${CURL_LIBRARY})
