[cmake-developers] [Review request] TopicFind GTK2_sigc++_c++11

[Daniele E. Domenichelli]

Hello,

Starting with some recent update on my system that updated sigc++ from
2.4.0 to 2.6.1, I noticed that a few GTK2Targets tests depending on
sigc++ are failing.
According to the sigc++ changelog, starting with version 2.5.1, sigc++
requires c++11 enabled, hence this patch.


  FindGTK2: Enable c++11 for sigc++ 2.5.1 or later
  https://cmake.org/gitweb?p=stage/cmake.git;a=commitdiff;h=f06bd1e


Can you please review it?



Cheers,
 Daniele
