<PackageName>_ROOT

New in version 3.12.

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.
