問題描述

Clion 使用conan插件配置了C++工程，然后想通過命令行進行編譯執行。
出現以下錯誤

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)

但是官方文檔的例子下載可以正常運行。

問題解決

閱讀官方文檔
https://docs.conan.io/2/tutorial/consuming_packages/the_flexibility_of_conanfile_py.html

由于Clion插件的conanfile.py 屬于Use the layout() method 這種方式
所以需要執行方式有點不一樣

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