cmake @3.12.3_0+universal configure failure with Xcode 10 on 10.13

[nikgervae]

Per the transcript below, when I try to install youtube-dl, at the point where "Configuring cmake" appears, a panel appears onscreen telling me I need to install Java for the java command-line tool. I have done this, and the error continues to appear. If I enter the command "which java", it replies: "/usr/bin/java", so it appears to be installed.

Your transcript shows that youtube-dl had already been successfully installed prior to you running sudo port install youtube-dl this time. It also shows that for some reason physfs is considered broken, and rebuilding it required cmake, which was unable to be configured for some reason.

/usr/bin/java is part of macOS and is always there, even if Java is not installed. If Java is installed, /usr/bin/java runs it; if not, it displays the dialog box you encountered.

Please attach the main.log file mentioned in the transcript so that we can see what the problem was. I don't think cmake requires Java (it didn't used to), so it might be something else.

FWIW, I get the same problem trying to install something fresh (port_cutleaves).

I had tried to update youtube-dl, got the failure described, and then I thought I had uninstalled it before trying to install "fresh", but of course none of the dependencies had been removed. This is why I was trying to install port_cutleaves.

Apparently one of cmake's configure checks is deciding to use the 10.14 SDK, even though you're on 10.13 and building for i386, which the 10.14 SDK doesn't support.

Well, I may have jumped the gun for solving the cmake problem, but I uninstalled youtube-dl and confirmed this time, then installed it fresh. I now have youtube-dl installed and running properly.
