c++ - 在 MacOS 上构建项目时，Cmake '无法在生成多个输出文件时指定 -o'

Question

我正在尝试在我的 Mac 上构建一个项目，我正在尝试移植一个程序。我正在使用 Cmake 编译和创建 Makefile 或 Xcode 项目。

如果我从构建目标子目录mkdir build && cd build && cmake ..（makeclang: error: cannot specify -o when generating multiple output files

我也尝试过使用 G++-11，但我得到了类似的错误g++-11: fatal error: cannot specify '-o' with '-c', '-S' or '-E' with multiple files。

我尝试通过使用禁用 Xcode 构建索引defaults write，并注释掉要包含的源中的头文件，以及将所有头文件移动到不同的目录。每次我得到同样的错误。

我有 Clang 12、G++ 11、Cmake 3.21.3 和 Make 3.81。这是项目https://github.com/CedarvilleCS/CedarLogic/blob/master/CMakeLists.txt的 GitHub 中的 make 文件。我很感激你们能给我的任何帮助，在此先谢谢你们。

编辑：cmake .. && make VERBOSE=1注释掉头文件后的输出（没有 Cmake 详细）

此外，该项目在 Windows 上编译得很好，所以我认为这不是代码错误（虽然我没有尝试自己编译它）。
