编译安装

cd jsoncpp
mkdir -p build/debug // 或者release
cd build/release
cmake -DCMAKE_BUILD_TYPE=release -DBUILD_STATIC_LIBS=on -DBUILD_SHARED_LIBS=on -DCMAKE_INSTALL_PREFIX=/usr/local ../.. //此命令编译静态库和动态库，设置安装路径为/usr/local
make
sudo make install

使用方法

单个文件使用

g++ file.cpp -I/usr/local  -L /usr/local/lib -l/usr/local/lib/libjsoncpp.a

cmake使用

在CMakeList.txt中添加下列语句

find_package(jsoncpp CONFIG REQUIRED)
if(jsoncpp_FOUND)
    message(STATUS "Found jsoncpp")
    message(STATUS "JSONCPP INCLUDE DIR: ${JSON_INC_PATH}")
endif(jsoncpp_FOUND)

target_include_directories(${NAME}
    PUBLIC
    ${JSONCPP_LIBRARIES}
    )

target_link_libraries(${NAME}
    PUBLIC
        jsoncpp_static # 似乎只用这个就可以
        )
