CMake Warning \(dev\) at CMP0144-common.cmake:[0-9]+ \(find_package\):
  Policy CMP0144 is not set: find_package uses upper-case <PACKAGENAME>_ROOT
  variables.  Run "cmake --help-policy CMP0144" for policy details\.  Use the
  cmake_policy command to set the policy and suppress this warning\.

  CMake variable FOO_ROOT is set to:

    [^
]*/Tests/RunCMake/find_package/PackageRoot/foo/cmake_root

  For compatibility, find_package is ignoring the variable, but code in a
  \.cmake module might still use it\.
