There will be no config.log and we do need to fix that error message
for ports that use CMake to build and for CMake itself.
If you could provide
"/usr/ports/devel/cmake-core/work/cmake-3.30.2/Bootstrap.cmk/cmake_bootstrap.log",
that would be extremely helpful.

Could you please also provide the output of the following commands:

make -C /usr/ports/devel/cmake-core -VCXX

c++ -###

All I can really tell for sure right now is the CMake bootstrap isn't
finding a working c++ compiler/installation on your system. The first
command is to determine the sanity of the CXX variable, because the
bootstrap uses this via the ports framework to determine the c++
compiler to test and works even if that variable were to be empty or
undefined (which it shouldn't be), but will fail if it is set to
something like clang++17 and devel/llvm17 is not installed. The second
is to see if the base c++ compiler can at least identify itself. Are
you using ccache? That shouldn't matter too much and I didn't see it
in your ports list, so I assume no, but it might help narrow things
down.
