CMAKE_EXPORT_PACKAGE_REGISTRY — CMake 4.4.0 Documentation

# CMAKE_EXPORT_PACKAGE_REGISTRY

Added in version 3.15.

Enables the `export(PACKAGE)` command when `CMP0090` is set to `NEW`.

The `export(PACKAGE)` command does nothing by default. In some cases it is desirable to write to the user package registry, so the `CMAKE_EXPORT_PACKAGE_REGISTRY` variable may be set to enable it.

If `CMP0090` is not set to `NEW` this variable does nothing, and the `CMAKE_EXPORT_NO_PACKAGE_REGISTRY` variable controls the behavior instead.
