.. versionadded:: 3.27

:command:find_package uses upper-case <PACKAGENAME>_ROOT variables.

In CMake 3.27 and above the :command:find_package(<PackageName>) command now searches prefixes specified by the upper-case :variable:<PACKAGENAME>_ROOT CMake variable and the :envvar:<PACKAGENAME>_ROOT environment variable in addition to the case-preserved :variable:<PackageName>_ROOT and :envvar:<PackageName>_ROOT variables used since policy :policy:CMP0074. This policy provides compatibility with projects that have not been updated to avoid using <PACKAGENAME>_ROOT variables for other purposes.

The OLD behavior for this policy is to ignore <PACKAGENAME>_ROOT variables if the original <PackageName> has lower-case characters. The NEW behavior for this policy is to use <PACKAGENAME>_ROOT variables.
