我有一个包含src和app文件夹的项目。每个文件夹包含一个CMakeLists.txt文件。该项目有一个CMakeLists.txt文件，该文件当前位于src文件夹中的add_subdirectory。这个通用的CMakeLists.txt使用src文件夹中的代码生成dll和lib并安装它。
问题是app有一个CMakeLists.txt文件，该文件编译了一个类，该类使用在运行src文件夹时安装的库。
1.如何配置app文件夹中的CMakeLists.txt，以使用从src文件夹运行CMakeLists.txt时创建和安装的库？

1. app文件夹中的CMakeLists.txt可以从通用CMakeLists.txt调用吗？还是应该在app文件夹中创建一个完全独立的CMAkeLIsts.txt？
