In cmake/modules/FindDEAL_II_CGAL.cmake
I print CGAL_DIR and remove QUIET
#
# CGAL requires C++17 and an externally configured Boost, otherwise the
# call to find_package(CGAL) will fail. Guard the call to FIND_PACKAGE to
# fail gracefully:
#
if(DEAL_II_HAVE_CXX17 AND NOT DEAL_II_FEATURE_BOOST_BUNDLED_CONFIGURED)
set(CGAL_DO_NOT_WARN_ABOUT_CMAKE_BUILD_TYPE ON)
#find_package(CGAL QUIET)
message(STATUS ${CGAL_DIR})
find_package(CGAL)
It prints CGAL_DIR correctly but shows some warnings and then error

<=== CGAL_DIR
CMake Warning at cmake/modules/FindDEAL_II_CGAL.cmake:43 (find_package):
By not providing "FindCGAL.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "CGAL", but
CMake did not find one.
Could not find a package configuration file provided by "CGAL" with any of
the following names:
CGALConfig.cmake
cgal-config.cmake
Add the installation prefix of "CGAL" to CMAKE_PREFIX_PATH or set
"CGAL_DIR" to a directory containing one of the above files. If "CGAL"
provides a separate development package or SDK, be sure it has been
installed.

CMake Error at cmake/macros/macro_configure_feature.cmake:112 (message):
Could not find the cgal library!
Please ensure that a suitable cgal library is installed on your computer.
If the library is not at a default location, either provide some hints for
autodetection,
$ CGAL_DIR="..." cmake <...>
$ cmake -DCGAL_DIR="..." <...>
or set the relevant variables by hand in ccmake.

I do see the file CGALConfig.cmake inside CGAL_DIR
$ pwd

--------------------------------------------------------------------------------$
find . -name CGALConfig.cmake
./lib/cmake/CGAL/CGALConfig.cmake
Does any of this shed some light on the issue ?
Thanks
