As a temporary workaround, replace cmake -E tar <options> by the equivalent tar <options> command to unpack *.tar.xz files in the ExternalProject.cmake module.
As a temporary workaround, replace cmake -E tar <options> by the
equivalent tar <options> command to unpack *.tar.xz files in the
ExternalProject.cmake module.

into CMake) that finally allows cmake -E tar ... to work on *.tar.xz
files gets propagated to a CMake release.
