我如何告诉IDE以特定的方式编译我的CMake项目？

Question

我有一个CMake (主要是C，带有一些C++)项目，其安装说明如下：

mkdir build
cd build
cmake /*some options*/ ../
make

如果我是从命令行编译的话，这是非常有效的。

我想使用IDE来编译这个程序，这样我就可以用图形调试器来调试它。但是，当我试图使用IDE编译时，我会得到链接器错误。

我不熟悉CMake的内部工作，因此不知道如何实现所期望的行为。事实上，我不确定这是否是一个CMake问题；也许这只是一个关于IDE配置的问题。如果有帮助的话，我使用的IDE是JetBrains‘CLion。

IDE中给出的错误是

您可以通过命令行编译将CLion指向构建目录。转到"File -> Settings -> Build，Execution，. -> Cmake“，并将”生成路径“指向您的”原始“生成目录。否则，CLion会在“”中生成自己的dir。即使将CLion指向另一个dir，它也可能会根据"Debug/Release“配置等其他参数在相同的设置选项卡上更改cmake变量。因为从您的cmake安装程序中，我们可以看到"Release“是默认的，只是切换可能会产生不同，甚至不需要切换build。
