 ChangeLog for TriBITS
 ----------------------------------------

+
+* **Changed:** Set CMake policy
+  [CMP0144](https://cmake.org/cmake/help/latest/policy/CMP0144.html) to `NEW`
+  (for versions of CMake 3.27+) so that `find_package(<PackageName> ...)` will
+  use upper case env var `<PACKAGENAME>_ROOT`.  Now, systems that are setting
+  uppercase env var names for standard packages will get picked in CMake
+  configures.

 ## 2025-02-17:
 
 * **Added:** Added support for header-only libraries with

tribits/core/common/TribitsCMakePolicies.cmake
