The 4.1.0 upgrade added two CXXFLAGS that only work with GCC, which
breaks the clang build of the testsuite (BIT7Z_WARNINGS_AS_ERRORS
defaults to BIT7Z_BUILD_TESTS, so -Werror is on whenever ptest is
enabled).
error: unknown warning option '-Wno-sfinae-incomplete'; did you mean
'-Wno-delete-incomplete'? [-Werror,-Wunknown-warning-option]
-Wsfinae-incomplete is a GCC 15+ diagnostic that clang does not have, so
only pass it when building with GCC.
cpm_cache/ghc_filesystem/include/ghc/filesystem.hpp:4090:41: error:
implicit conversion changes signedness: 'int' to 'mode_t'
(aka 'unsigned int') [-Werror,-Wsign-conversion]
Upstream declares the ghc::filesystem include directory as a SYSTEM one
(target_include_directories(ghc_filesystem SYSTEM INTERFACE ...) in
cmake/Dependencies.cmake), which keeps warnings from that header quiet.
Passing it as a plain -I undoes that, so use -isystem instead.
There is nothing to upgrade to here, 4.1.0 is the latest release and
upstream master is a single documentation commit ahead of it.
