Cona编译问题

问题描述

Clion 使用conan插件配置了C++工程，然后想通过命令行进行编译执行。
出现以下错误

CMake Error at /usr/local/Cellar/cmake/3.30.1/share/cmake/Modules/CMakeDetermineSystem.cmake:152 (message):Could not find toolchain file: conan_toolchain.cmake
Call Stack (most recent call first):CMakeLists.txt:2 (project)

但是官方文档的例子下载可以正常运行。
https://docs.conan.io/2/tutorial/consuming_packages/build_simple_cmake_project.html

问题解决

阅读官方文档
https://docs.conan.io/2/tutorial/consuming_packages/the_flexibility_of_conanfile_py.html

由于Clion插件的conanfile.py 属于Use the layout() method 这种方式
所以需要执行方式有点不一样

$ conan install . --build=missing
$ cd build/Release
$ source ./generators/conanbuild.sh
