patches/packages/boost-1.78.0-x86_64-3_slack15.0.txz: Rebuilt.
Get rid of hardcoded temporary paths in the cmake files.
Since these paths point to a location that an unprivileged user could
create and populate with files that could be picked up during a build,
it's possible this bug could be used for malicious purposes.
Thanks to jmacloue.
(* Security fix *)
