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：
image.png
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.
通过cmakelists.txt配置的完整脚本**
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)
add_executable(vcpkg_catch_demo main.cpp)
