This helps with locating the header/library, but it fails to compile in
poudriere on 12.0-RELEASE-p7:
x.cpp:213:15: error: no member named 'is_symlink' in
'std::experimental::filesystem::v1::directory_entry'
if (entry.is_symlink())
~~~~~ ^
It looks like 12.0-RELEASE-p7 is technically broken, because it doesn't
include is_symlink().
