C++ cmake文件（复制…）会导致复制旧文件
我正在尝试设置C++ cmake文件（复制…）会导致复制旧文件,c++,cmake,C++,Cmake,我正在尝试设置cmake将头文件复制到特定位置，以便在使用库时可以使用中心位置访问头文件。我正在使用一个最小的代码集来测试这个。目录结构如下所示： src/ ├── CMakeLists.txt ├── codepack │ ├── CMakeLists.txt │ ├── package.xml │ └── src │ └── code.cpp └── libpack ├── CMakeLists.txt ├── package.xml └──
