OK, found it. For Fedora based distros you now need:
 clang clang-devel llvm-devel
And for Debian based distros you need:
 clang libclang-dev llvm

But on Deban based systems the headers and libraries are installed in
an llvm version specific location. You can find them using
llvm-config.  Luckily this also works for the unversioned llvm on
Fedora bases systems:

(debian) llvm-config --cxxflags
-I/usr/lib/llvm-14/include -std=c++14   -fno-exceptions -D_GNU_SOURCE -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS -D__STDC_LIMIT_MACROS

(debian) llvm-config --ldflags --system-libs
-L/usr/lib/llvm-14/lib

(fedora) llvm-config --cxxflags
-I/usr/include -std=c++17   -fno-exceptions -funwind-tables -D_GNU_SOURCE -D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS -D__STDC_LIMIT_MACROS
(fedora) llvm-config --ldflags --system-libs
-L/usr/lib64

I don't know how hard that is to incorporate in the configure/automake
scripts.

Cheers,

Mark
