[Cmake-commits] [cmake-commits] hoffman committed check_stdcall_func.m4 NONE 1.1 la_uid_t.m4 NONE 1.1

[cmake-commits at cmake.org]

Update of /cvsroot/CMake/CMake/Utilities/cmlibarchive/build/autoconf
In directory public:/mounts/ram/cvs-serv26614/Utilities/cmlibarchive/build/autoconf

Added Files:
	check_stdcall_func.m4 la_uid_t.m4 
Log Message:
Switch to using libarchive from libtar for cpack and cmake -E tar

This allows for a built in bzip and zip capability, so external tools 
will not be needed for these packagers.  The cmake -E tar xf should be
able to handle all compression types now as well.
