# CMP0062

Added in version 3.3.

Disallow `install()` of `export()` result.

The `export()` command generates a file containing Imported Targets, which is suitable for use from the build directory. It is not suitable for installation because it contains absolute paths to buildsystem locations, and is particular to a single build configuration.

The `install(EXPORT)` generates and installs files which contain Imported Targets. These files are generated with relative paths (unless the user specifies absolute paths), and are designed for multi-configuration use. See Creating Packages for more.

CMake 3.3 no longer allows the use of the `install(FILES)` command with the result of the `export()` command.

The `OLD` behavior for this policy is to allow installing the result of an `export()` command. The `NEW` behavior for this policy is not to allow installing the result of an `export()` command.

This policy was introduced in CMake version 3.3. It may be set by `cmake_policy()` or `cmake_minimum_required()`. If it is not set, CMake warns, and uses `OLD` behavior.

Note

The `OLD` behavior of a policy is `deprecated by definition` and may be removed in a future version of CMake.
