Comment:

 Don't make a fake 10.14 SDK linked to the 10.15 one. That is asking for
 trouble when features are detected at configure time but then don't exist
 at runtime. (If everything checked for weak-linked symbols that wouldn't
 be a problem, but very little in the open source world does.) The real
 10.14 SDK should be installed by the Command Line Tools, and base is
 setting appropriate -isysroot flags to use it.

 It looks like the issue is that PDAL has -isysroot hardcoded in its
 config. That should be removed.
