# Utility macros for copying files
#
# Last update: 9th January 2013
#
#
# Create a target for copying files.
#
if (NOT TARGET copy_files)
add_custom_target(copy_files ALL)
endif()
#
# Create a variable to keep track of the number of copy files targets created.
#
if (NOT copy_target_count)
set(copy_target_count 0)
endif (NOT copy_target_count)
set(copy_target_count ${copy_target_count} CACHE INTERNAL "" FORCE)

# Macro: COPY_FILES
#-------------------------------------------------------------------------------
#
# Description:
# Adds a command to the build target 'copy_files' which copies files matching
# the specifeid globbing expression from the specified source directory to
# the specified destination directory.
#
# Usage:
# COPY_FILES(SRC_DIR GLOB_PAT DST_DIR)
#
# Arguments:
# - SRC_DIR : The source directory containging files to be copied.
# - GLOB_PAT : globbing expression used to match files for copying.
# - DST_DIR : The destination directory where files are to be copied to.
#
# Example:
# copy_files(${CMAKE_CURRENT_SOURCE_DIR} *.dat ${CMAKE_CURRENT_BINARY_DIR})
# Will copy all files in the current source directory with the extension
# '.dat' into the current binary directory.
#
