Summary0014504: libarchive supports 7-Zip, Add 7-Zip support to cmake
DescriptionAs I understand cmake uses libarchive for inflating tar.gz files. This is useful within ExternalProject_Add as you can pass in a URL of a tar.gz and cmake handles it. Since libarchive _also_ supports inflating 7z formats can cmake also support it?

For example, I wanted to use ExternalProject_Add with a custom build & install step to setup the libusbx binaries [1] on windows but they are in 7z format.

[1] http://sourceforge.net/projects/libusbx/files/releases/1.0.17/binaries/ [^]
Steps To ReproduceExternalProject_Add(
  URL <path to 7z archive>
  ...
)

Is not supported
Additional Informationlibarchive supports 7-zip , https://github.com/libarchive/libarchive [^]
TagsNo tags attached.

IIUC libarchive requires liblzma from http://tukaani.org/xz/ [^] to support 7z formats. This will have to be brought in to the CMake build similar to these:

 Utilities/cmbzip2/
 Utilities/cmcompress/
 Utilities/cmzlib/

with corresponding support for using a system-installed liblzma too.

The xz/lzma support keeps poping up as feature request.
See related bug/feature requests.

After a contributor ported liblzma to C89/90 for us we are finally able to implement lzma support in "cmake -E tar" and ExternalProject:

 CMake: Enable use of liblzma in libarchive
 http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=8436d181 [^]

 ExternalProject: Recognize lzma-compressed files
 http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=56e6975c [^]
