# <PackageName>_ROOT

Calls to `find_package(<PackageName>)` will search in prefixes specified by the `<PackageName>_ROOT` CMake variable, where `<PackageName>` is the name given to the `find_package` call and `_ROOT` is literal. For example, `find_package(Foo)` will search prefixes specified in the `Foo_ROOT` CMake variable (if set). See policy `CMP0074`.

This variable may hold a single prefix or a semicolon-separated list of multiple prefixes.

See also the `<PackageName>_ROOT` environment variable.
