ecbuild CI test failure - could not find compatible configuration file

[figi44]

CI fails on all platforms during testing phase (see https://github.com/ecmwf/ecbuild/actions/runs/4542140680). I noticed there was a new version of CMake released (3.26.0 logs) since the last successful run (3.25.3 logs), maybe it's related?

The following tests FAILED:
13 - bundle-subproj (Failed)
14 - bundle-override-features (Failed)
24 - project_import (Failed)

all with the following error:

23/24 Test #24: project_import ......................***Failed    0.03 sec
  CMake Error at CMakeLists.txt:3 (find_package):
    Could not find a configuration file for package "ecbuild" that is
    compatible with requested version "3.4".
  
    The following configuration files were considered but not accepted:
  
      /home/runner/work/ecbuild/ecbuild/build/ecbuild-config.cmake, version: 3.7.2 (64bit)
