find_package(dav1d REQUIRED)是CMake中用于查找dav1d库的命令。如果你想在你的项目中使用dav1d库,你需要确保已经安装这个库,并且在CMakeLists.txt文件中添加以下代码:
```
find_package(dav1d REQUIRED)
```
这个命令将自动查找dav1d库的位置,并将其添加到你的项目中。如果dav1d库没有被正确安装,你将会收到一个错误消息。在这种情况下,你需要手动安装dav1d库,并确保它可以被CMake正确识别。

find_package(dav1d REQUIRED)
This is a CMake command to find and include the dav1d library in a CMake project.
The `find_package` command is used to locate and import the configuration file for a CMake package. In this case, it is searching for the `dav1d` package.
The `REQUIRED` argument specifies that the package is necessary for the project to build and should throw an error if it cannot be found.
Once the package is found, CMake will create variables that can be used to link against the library and include its headers. For example, `dav1d_LIBRARIES` and `dav1d_INCLUDE_DIRS`.
