Hi,
I would like to propose two new modules for inclusion in CMake:
FindOpenCL to find OpenCL and FindHg for Mercurial (see attached.)
FindOpenCL is written in similar spirit to FindOpenGL, while FindHg is
basically the equivalent of FindSubversion for Mercurial.
The modules have been tested on Windows, Linux, and Mac, using a variety
of OpenCL runtimes.
I would be happy to be the maintainer of these modules, if they get
accepted into the CMake distribution.
Cheers,
Matthäus

# FindHg
# ------
#
# Extract information from a mercurial working copy
#
# The module defines the following variables:
#
# ::
#
# Hg_EXECUTABLE - path to mercurial command line client
# Hg_FOUND - true if the command line client was found
#
#
# If the command line client executable is found the following macro is defined:
#
# ::
#
# Hg_WC_INFO(<dir> <var-prefix>)
#
# Hg_WC_INFO extracts information of a mercurial working copy
# at a given location. This macro defines the following variables:
#
# ::
#
# <var-prefix>_WC_CHANGESET - current changeset
# <var-prefix>_WC_REVISION - current revision
#
# Example usage:
#
# ::
#
# find_package(Hg)
# if(Hg_FOUND)
# Hg_WC_INFO(${PROJECT_SOURCE_DIR} Project)
# message("Current revision is ${Project_WC_REVISION}")
