recommended that you compile it with clang and clang++ as your [Objective-]C and
[Objective-]C++ compilers.

It is recommended that you use the LLVM runtime and unwinder or a recent version
of GCC (>= 14) on GNU/Linux to avoid a
[bug](https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114843) in GCC and the libgcc
unwinder.

If CompilerRT and libunwind are installed on your machine use
`-DCMAKE_EXE_LINKER_FLAGS="-rtlib=compiler-rt -unwindlib=libunwind"`.
