From 88e6447e1914d87670269092b3021b8ea3d0dba1 Mon Sep 17 00:00:00 2001 From: Alex Neundorf Date: Wed, 25 Aug 2010 21:53:16 +0200 Subject: Add macro ADD_FEATURE_INFO() and improve docs. ADD_FEATURE_INFO() can be used to set the info for a feature, e.g. an option(). set_feature_info() has been renamed to set_package_info(), since this is about found or not found packages. For compatiblity set_feature_info() is still provided.
