  -----------
  Set new CMake policy for upper-case <NAME>_ROOT variables (#1642)

In CMake 3.27 and above the find_package(<PackageName>) command now
searches prefixes specified by the upper-case <PACKAGENAME>_ROOT CMake
variable and the <PACKAGENAME>_ROOT environment variable in addition to
the case-preserved <PackageName>_ROOT and <PackageName>_ROOT variables
used since 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.
