 `-lc++-experimental` doesn't exist in OpenBSD but the LLVM driver still tries to link against it, to solve just symlink `ln -s /usr/lib/libc++.a /usr/lib/libc++experimental.a`. Builds are currently not working due to lack of `std::jthread` and such, either compile libc++ manually or wait for ports to catch up.

 Install `pkgin` if not already `pkg_add pkgin`, see also the general [pkgsrc guide](https://www.netbsd.org/docs/pkgsrc/using.html).

 System provides a default `g++-10` which doesn't support the current C++ codebase; install `clang-19` with `pkgin install clang-19`. Or install `gcc14` (or `gcc15` with current pkgsrc). Provided that, the following CMake commands may work:

 However, pkgsrc is highly recommended, see [getting pkgsrc](https://iso.us.netbsd.org/pub/pkgsrc/current/pkgsrc/doc/pkgsrc.html#getting). You must get `current` not the `2025Q2` version.
 
+`QtCore` on NetBSD is included, but due to misconfigurations(!) we MUST include one of the standard headers that include `bits/c++config.h`, since source_location (required by `QtCore`) isn't properly configured to intake `bits/c++config.h` (none of the experimental library is). This is a bug with NetBSD packaging and not our fault, but alas.
