<PackageName>_ROOT — CMake 4.4.0 Documentation

# <PackageName>_ROOT

Added in version 3.12.

Calls to `find_package(<PackageName>)` will search in prefixes specified by the `<PackageName>_ROOT` CMake variable, where `<PackageName>` is the (case-preserved) 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.

<PACKAGENAME>_ROOT

  Added in version 3.27.

  Calls to `find_package(<PackageName>)` will also search in prefixes specified by the upper-case `<PACKAGENAME>_ROOT` CMake variable. See policy `CMP0144`.
