Building with clang does not work anymore

Describe the bug

Building with clang (on my system 18.1.8) does not work anymore when -DUNIT_TESTING is active.
The linker has some problem with the unit tests apparently:

/usr/bin/ld: src/iso15118/libiso15118.a(logging.cpp.o): in function `__llvm_gcov_writeout':
logging.cpp:(.text+0xf9a): undefined reference to `llvm_gcda_start_file'
/usr/bin/ld: logging.cpp:(.text+0xfe2): undefined reference to `llvm_gcda_emit_function'
/usr/bin/ld: logging.cpp:(.text+0xffe): undefined reference to `llvm_gcda_emit_arcs'
/usr/bin/ld: logging.cpp:(.text+0x1017): undefined reference to `llvm_gcda_summary_info'
/usr/bin/ld: logging.cpp:(.text+0x101c): undefined reference to `llvm_gcda_end_file'
/usr/bin/ld: src/iso15118/libiso15118.a(logging.cpp.o): in function `__llvm_gcov_init':
logging.cpp:(.text+0x1569): undefined reference to `llvm_gcov_init'
[...]

Building worked until and including git hash: 063944bfa141a86eddb298da2a6c9767ad6e5f57. The next commit df95c232fdd47881d218f82cf1750aba5d9f9336 added something that clang or the linker does not like.

To Reproduce

1. Checkout the actual main (hash: a50c9af1296f04881a3be5d00fe4e02b1559521b)
2. Run: cmake -S . -B build -G Ninja -DBUILD_TESTING=ON -DCMAKE_EXPORT_COMPILE_COMMANDS=ON -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++
3. Run: ninja -C build

Anything else?
