cmake - 如何构建 libobs 作为 obs-studio-node 模块的依赖项？

Question

我正在尝试obs-studio-node。
该模块需要libobs作为依赖项。在构建这个模块时，它会下载一个预构建的版本，libobs如果没有指定。我们可以指定自定义libobs，如中所述README.md

我按照这些步骤构建libobs. 这些步骤列在README.md

1. git clone https://github.com/stream-labs/obs-studio
2. cd obs-studio
3. git submodule update --init --recursive
4. mkdir build
5. cd build
6. cmake .. -DENABLE_UI=false -DDepsPath="C:\Users\alokm\Downloads\dependencies2019\win64" -DENABLE_SCRIPTING=false -G"Visual Studio 16 2019" -A x64
7. cmake --build .
8. cpack -G ZIP

最后一步 ( cpack -G ZIP) 因错误而失败

PS C:\Users\alokm\tmp\streamlabs\obs-studio\build> cpack -G ZIP
CPack: Create package using ZIP
CPack: Install projects
CPack: - Install project: obs-studio []

CPack Error: Error when generating package: OBS Studio (64bit)

我猜obs-studio不支持cpack所以它失败了。
如何libobs为obs-studio-nodemobule 建立我的自定义？

Answer 1

检查您构建的确切配置。CPack 的输出尝试安装Release配置。但是，您没有提到任何项目配置何时进行（并且设置一些默认值可能取决于项目）。

尝试明确添加您想要的内容：

$ cmake .. -DENABLE_UI=false -DDepsPath="C:\Users\alokm\Downloads\dependencies2019\win64" -DENABLE_SCRIPTING=false -DCMAKE_CONFIGURATION_TYPES=Release -G "Visual Studio 16 2019" -A x64
$ cmake --build . --config Release
