From 7df031e1ffe409573753585ba2f1a82ff707ad7e Mon Sep 17 00:00:00 2001 From: Nathan Rossi Date: Tue, 21 Feb 2017 23:17:28 +1000 Subject: package.bbclass: Add SHLIB detection support for mingw targets Add support to detect dll files as shared objects as well as process Windows .dll and .exe files to determine the runtime libraries dependencies. This implementation is sufficient to detect and map runtime library dependencies between packages. And does not implement any version naming conventions that might apply for .dll files (e.g. lib*-x.dll).
