Building on Gentoo

Hello, trying to build Serenity on Gentoo I am getting:

Seems like cmake doesn't detect compiler ABI correctly, but not sure what to do about it. Thanks.

That assert is printed by your cmake executable. So I guess that's a bug in this specific version. You might want to try using Toolchain/BuildCmake.sh instead.

Right, might be worth reporting this one upstream to CMake if you can reduce it.. though our CMake setup is a bit complex to just dive in and minimize a generator expression evaluation crash.
