Working on macOS 10.15.7 Catalina. Is this old enough? ;) |
|
Our oldest supported OS is Mojave. |

find_package(LibLZMA) only defines a target as of CMake version 3.14 (according to the documentation anyway) but our minimum is 3.13. |

Homebrew does not install header-less versions of zstd. You just need to use the include directory returned by pkg-config to find them.
For LZMA, macOS does include a headerless dylib, but FindLibLZMA searches for the header and marks LZMA as not found unless the header is also found. Once again, the issue was us ignoring the required include directories.
Note: Before merging, we should make sure buildbot builds still run on older macOSes, since this could affect what system libraries get used, and Homebrew libs are not compiled with backwards compatibility enabled
