libevent windows编译

准备环境

下载libevent

https://github.com/libevent/libevent.git

修改CMakeLists.txt

打开libevent主目录下的CMakeLists.txt文件，找到find_package(OpenSSL REQUIRED)的位置，
在其上方添加openssl的安装信息，已告知libevent如何找到openssl, 改动完成后，如下：

    ...
    ...
    set(OPENSSL_ROOT_DIR "C:/toolchain/OpenSSL-Win64")
    set(OPENSSL_LIBRARIES "${OPENSSL_ROOT_DIR}/lib")
    set(OPENSSL_INCLUDE_DIR "${OPENSSL_ROOT_DIR}/include")
    find_package(OpenSSL REQUIRED)
    ...
    ...

配置

cmake -Bbuild -DCMAKE_INSTALL_PREFIX=sdk .

-DCMAKE_INSTALL_PREFIX=sdk 选项表示安装目录为sdk，INSTALL后的所有文件位于此目录，

配置输出参考如下：

 G:\Code\libevent> cmake -Bbuild  -DCMAKE_INSTALL_PREFIX=sdk .

编译

打开build目录下的vs工程libevent.sln
选择ALL_BUILD生成, 以进行编译
选择INSTALL生成, 以进行安装库文件、头文件、所需的cmake文件等
