安装vcpkg

git clone https://github.com/microsoft/vcpkg
cd vcpkg
./bootstrap-vcpkg.sh

安装catch2

./vcpkg install catch2

配置vcpkg所有工程可用

./vcpkg integrate install

项目配置

假设项目名称是：vcpkg_catch_demo

配置vcpkg工具链

通过clion GUI配置

在Clion/Preferences/Build,Execution,Deployment/Cmake/CMake options中填入以下信息：
-DCMAKE_TOOLCHAIN_FILE=/Users/hualongzhang/vcpkg/scripts/buildsystems/vcpkg.cmake，如图：

通过cmakelists.txt配置

set(CMAKE_TOOLCHAIN_FILE "/Users/hualongzhang/vcpkg/scripts/buildsystems/vcpkg.cmake")
project(vcpkg_catch_demo)

设置CMAKE_TOOLCHAIN_FILE要在project()命令之前

配置catch2

在项目的cmakelists.txt中加入以下内容

find_package(Catch2 CONFIG REQUIRED)
target_link_libraries(vcpkg_catch_demo PRIVATE Catch2::Catch2)

• 要把以上两句放在add_executable后面，否则会出现以下错误：

CMake Error at CMakeLists.txt:8 (target_link_libraries):
  Cannot specify link libraries for target "vcpkg_catch_demo" which is not built by this
  project.

• 以下错误为没有配置好vcpkg工具链，如果已经严格按以上配置，但是还是出现该错误，则可以删除目录cmake-build-debug后，再右键点击CMakelists.txt，选择：Reload Cmake Project：

CMake Error at CMakeLists.txt:6 (find_package):
  Could not find a package configuration file provided by "Catch2" with any
  of the following names:

    Catch2Config.cmake
    catch2-config.cmake

  Add the installation prefix of "Catch2" to CMAKE_PREFIX_PATH or set
  "Catch2_DIR" to a directory containing one of the above files.  If "Catch2"
  provides a separate development package or SDK, be sure it has been
  installed.

cmake_minimum_required(VERSION 3.17)
set(CMAKE_TOOLCHAIN_FILE "/Users/hualongzhang/vcpkg/scripts/buildsystems/vcpkg.cmake")
project(vcpkg_catch_demo)

set(CMAKE_CXX_STANDARD 20)
