From 44fd71decbca329d9cdfc196a073a62668af53f2 Mon Sep 17 00:00:00 2001 From: Brad King Date: Mon, 26 Jan 2015 13:28:31 -0500 Subject: [PATCH] cmake: Teach "-E tar" command a "--files-from=" option Read file names from the lines of a specified file. Reject input lines starting in '-' to leave room for option parsing to be added later. Add just '--add-file=' now to allow files starting in '-' to be specified. --- Help/release/dev/cmake-E-tar-files-from.rst | 6 +++ Source/cmcmd.cxx | 53 +++++++++++++++++++
