CMake报错：add_subdirectory not given a binary directory but the given source directory

Posted 2023-05-07

参考技术A add_subdirectory 命令，可以将指定的文件夹加到build任务列表中。
如果你的目录结构如下：

main 是主工程的CMake目录，需要添加子目录模块 sub1 ,那么语法如下：
默认情况下是添加当前目录的子目录，用法如下：

如果还需要依赖外部目录(即不是主目录的子目录)，就需要指定绝对路径，如下：

不指定绝对路径就会报如下错误：

Steinberg VST3 项目生成器 CMake 中的错误 - “add_subdirectory 调用的参数数量不正确”

【中文标题】Steinberg VST3 项目生成器 CMake 中的错误 - “add_subdirectory 调用的参数数量不正确”

【英文标题】：Error in Steinberg VST3 Project Generator CMake - "add_subdirectory called with incorrect number of arguements"

【问题描述】：

我正在尝试使用 Steinberg VST3 项目生成器创建一个基本的新乐器插件，但出现以下错误：

CMakeLists.txt:12 (add_subdirectory) 处的 CMake 错误： add_subdirectory 调用的参数数量不正确

CMakeLists.txt:13 (smtg_enable_vst3_sdk) 处的 CMake 错误： 未知的 CMake 命令“smtg_enable_vst3_sdk”。

我该如何解决这个问题？ 我附上了生成器设置的图像，并在下面粘贴了完整的脚本输出。

【参考方案1】：

我在尝试为 cmake Visual Studio 2019 生成的 Windows 10 上遇到了同样的错误，对我来说问题是我的 VST3 SDK 和输出目录的文件路径中的目录名称中有一个空格（它们是在同一目录中）。我删除了目录名称中的空格并且它起作用了。您的目录名称“EXTRA STORAGE”中有一个空格。删除该空间，如“EXTRA_STORAGE”或将文件移动到另一个没有空间的目录。这对我有用。
