CMake Warning at tests/CMakeLists.txt:21 (find_package):
  By not providing "Findcatch2.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "catch2", but
  CMake did not find one.

  Could not find a package configuration file provided by "catch2" with any
  of the following names:

    catch2Config.cmake
    catch2-config.cmake

  Add the installation prefix of "catch2" to CMAKE_PREFIX_PATH or set
  "catch2_DIR" to a directory containing one of the above files.  If "catch2"
  provides a separate development package or SDK, be sure it has been
  installed.

On CI everything worked fine, so presumably letter-case may be at fault.

Yes, according to catch2's contents shown at ​https://ports.macports.org/port/catch2/details/ the file is called Catch2Config.cmake, not catch2Config.cmake.
