Subject: [CMake] Fixing the 3-stage cmake cache.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=86ce4f64a9e091653c2f3a24233108b8248e0ee9;p=clang

[CMake] Fixing the 3-stage cmake cache.

I had hoped this would work from a single cache file, but turns out there is a bug I can't quite figure out relating to passing list arguments to recursive CMake invocations.

This change works around that.
