Workarounds

90% success Install a newer version of the package that meets the requirement. For example, on Ubuntu: sudo apt-get install mypackage=2.0.0 Or build from source: git clone https://github.com/example/mypackage.git -b v2.0.0 cd mypackage && mkdir build && cd build cmake .. && sudo make install
```

Or build from source:

cd mypackage && mkdir build && cd build
cmake .. && sudo make install
```
85% success Specify a lower version requirement in find_package if the API is backward-compatible: find_package(MyPackage 1.2.3 REQUIRED) Or use EXACT to pin to a specific version: find_package(MyPackage 2.0.0 EXACT REQUIRED)
```
Specify a lower version requirement in find_package if the API is backward-compatible:

find_package(MyPackage 1.2.3 REQUIRED)

Or use EXACT to pin to a specific version:

find_package(MyPackage 2.0.0 EXACT REQUIRED)
```

中文步骤

安装满足要求的较新版本的包。例如，在 Ubuntu 上：

sudo apt-get install mypackage=2.0.0

或从源码构建：

git clone https://github.com/example/mypackage.git -b v2.0.0
cd mypackage && mkdir build && cd build
cmake .. && sudo make install

如果 API 向后兼容，可以在 find_package 中指定较低的版本要求：

find_package(MyPackage 1.2.3 REQUIRED)

或使用 EXACT 固定到特定版本：

find_package(MyPackage 2.0.0 EXACT REQUIRED)

Dead Ends

Common approaches that don't work:

Delete the package config file and let CMake search again 80% fail
CMake will find the same file again if it's the only one; deleting it may break other projects that depend on it.
Modify MyPackageConfigVersion.cmake to report a higher version 95% fail
Tampering with version files causes silent runtime errors due to API incompatibility; dangerous and unsupported.
