From f33c6f37a8226c67a199181a8721f09983089448 Mon Sep 17 00:00:00 2001 From: Frederik Gladhorn Date: Thu, 14 Jan 2016 13:01:39 +0100 Subject: Work around MinGW-make's magic prefixing of paths. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When building QNX on MS-Windows, make magically adds the Msys root as prefix to variables whose values look like paths; this applies to both environment variables and variables given values on the command-line. When we don't actually want to install under the Msys root, this is unwelcome "help". So (for MinGW's make) support a magic prefix of our own, @msyshack@, that'll make a path value for INSTALL_ROOT not look like a path to make; we can then strip it off when we come to use it.
