我有一个导出的库，现在想用find_package()导入。如果我给出了FooConfig.cmake文件的路径，那行得通。
cmake的配置步骤效果很好，但是在生成步骤中cmake抱怨
CMake Error in CMakeLists.txt:
Imported target "Foo" includes non-existent path
"Debug/include/Foo"
in its INTERFACE_INCLUDE_DIRECTORIES. Possible reasons include:
* The path was deleted, renamed, or moved to another location.
* An install or uninstall procedure did not complete successfully.
* The installation package was faulty and references files it does not
provide.
因此在目标中仅存储了相对路径，这实际上很好，因为这样库的整个安装都是可重定位的。 在我看来，通过find_package导入库时，我需要设置安装前缀。有人知道怎么做吗？
