# 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.
