Re: [sigc] How to test for libsigc++ with CMake?

Below is my find script for sigc++. It's my understanding this approach
is generally preferred because it will attempt to use pkg-config if it
can, but will still search for the required things if it cannot. 

# - Try to find SigC++-2.0
# Once done, this will define
#  SigC++_FOUND - system has SigC++
#  SigC++_INCLUDE_DIRS - the SigC++ include directories
#  SigC++_LIBRARIES - link these to use SigC++


# Use pkg-config to get hints about paths
libfind_pkg_check_modules(SigC++_PKGCONF sigc++-2.0)

# Main include dir
  NAMES sigc++/sigc++.h
  PATH_SUFFIXES sigc++-2.0

# Glib-related libraries also use a separate config header, which is in
lib dir
  NAMES sigc++config.h
  PATH_SUFFIXES lib/sigc++-2.0/include

libfind_library(SigC++ sigc 2.0)

# Set the include dir variables and the libraries and let
libfind_process do the rest.
# NOTE: Singular variables for this library, plural for libraries this
this lib depends on.

Yet, I failed to get a hold of a way to write cmake scripts that test if libsigc++ is present in a system, which version is present and include it in the build process.
