c++ - 在 Clion IDE 中使用 Crypto++

Question

我在新安装的 Clion IDE 中编译正确的应用程序时遇到一些问题。早些时候我使用了 Code::Blocks 并全部编译成功。项目使用pthread和Crypto++库。我已经将它们安装在我的 Ubuntu 15.04 上。并使用 -pthread 标志编译 Clion 项目。但它找不到 crypto++ 库。如何解决这个问题？

我的 CMake 文件:

cmake_minimum_required(VERSION 3.3)
project(Chat)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -pthread")

set(SOURCE_FILES

Answer 1

我在 CMakeLists.txt 中的 add_executable 之后执行了以下操作来解决该问题:

target_link_libraries(Chat /usr/lib/libcrypto++.a)
