build failure with gcc 12

[ltalirz]

I notice I can build scine-utilities fine with gcc 11.3.0 but with 12.2.0 I get errors like

>> 828    /tmp/root/spack-stage/spack-stage-scine-utilities-6.0.0-tyayl46ngbiux5dg6kqdx7fubcop3agi/spack-src/src/Utils/Utils/IO/ChemicalFileFormats/ChemicalFileHandler.cpp:24:20: error: 'unique_ptr' is not a member of 'std'

I don't fully understand what's happening here - unique_ptr should have been introduced with c++11 and  I see the c++ standard is set to 17 here

development-utils/cmake/ComponentSetup.cmake

Line 31 in 0ffba74

set(CMAKE_CXX_STANDARD 17 PARENT_SCOPE)

@nabbelbabbel points out to add

 "include <memory>"

in the corresponding ChemicalFileHandler.cpp source file
