" file(WRITE filename \"message to write\"... )\n"
" file(APPEND filename \"message to write\"... )\n"
" file(READ filename variable [LIMIT numBytes] [OFFSET offset] [HEX])\n"
" file(STRINGS filename variable [LIMIT_COUNT num]\n"
" [LIMIT_INPUT numBytes] [LIMIT_OUTPUT numBytes]\n"
" [LENGTH_MINIMUM numBytes] [LENGTH_MAXIMUM numBytes]\n"
" [NEWLINE_CONSUME] [REGEX regex]\n"
" [NO_HEX_CONVERSION])\n"
" file(GLOB variable [RELATIVE path] [globbing expressions]...)\n"

" file(DOWNLOAD url file [TIMEOUT timeout] [STATUS status] [LOG log])\n"
"WRITE will write a message into a file called 'filename'. It "
"overwrites the file if it already exists, and creates the file "
"if it does not exist.\n"
"APPEND will write a message into a file same as WRITE, except "
"it will append it to the end of the file\n"
"READ will read the content of a file and store it into the "
"variable. It will start at the given offset and read up to numBytes. "
"If the argument HEX is given, the binary data will be converted to "
"hexadecimal representation and this will be stored in the variable.\n"
"STRINGS will parse a list of ASCII strings from a file and "
"store it in a variable. Binary data in the file are ignored. Carriage "
"return (CR) characters are ignored. It works also for Intel Hex and "
"Motorola S-record files, which are automatically converted to binary "
"format when reading them. Disable this using NO_HEX_CONVERSION.\n"
"LIMIT_COUNT sets the maximum number of strings to return. "
"LIMIT_INPUT sets the maximum number of bytes to read from "
"the input file. "
"LIMIT_OUTPUT sets the maximum number of bytes to store in the "
"output variable. "
"LENGTH_MINIMUM sets the minimum length of a string to return. "
"Shorter strings are ignored. "
"LENGTH_MAXIMUM sets the maximum length of a string to return. Longer "
"strings are split into strings no longer than the maximum length. "
"NEWLINE_CONSUME allows newlines to be included in strings instead "
"of terminating them.\n"
"REGEX specifies a regular expression that a string must match to be "
"returned. Typical usage \n"
" file(STRINGS myfile.txt myfile)\n"
"stores a list in the variable \"myfile\" in which each item is "
"a line from the input file.\n"
"GLOB will generate a list of all files that match the globbing "
"expressions and store it into the variable. Globbing expressions "
"are similar to regular expressions, but much simpler. If RELATIVE "
"flag is specified for an expression, the results will be returned "
"as a relative path to the given path.\n"
"Examples of globbing expressions include:\n"
" *.cxx - match all files with extension cxx\n"
" *.vt? - match all files with extension vta,...,vtz\n"
" f[3-5].txt - match files f3.txt, f4.txt, f5.txt\n"
"GLOB_RECURSE will generate a list similar to the regular GLOB, except "
"it will traverse all the subdirectories of the matched directory and "
"match the files. Subdirectories that are symlinks are only traversed "
"if FOLLOW_SYMLINKS is given or cmake policy CMP0009 is not set to NEW. "
"See cmake --help-policy CMP0009 for more information.\n"
"Examples of recursive globbing include:\n"
" /dir/*.py - match all python files in /dir and subdirectories\n"
"MAKE_DIRECTORY will create the given directories, also if their parent "
"directories don't exist yet\n"
"RENAME moves a file or directory within a filesystem, "
"replacing the destination atomically."
"\n"
"REMOVE will remove the given files, also in subdirectories\n"
"REMOVE_RECURSE will remove the given files and directories, also "
"non-empty directories\n"
"RELATIVE_PATH will determine relative path from directory to the given"
" file.\n"
"TO_CMAKE_PATH will convert path into a cmake style path with unix /. "
" The input can be a single path or a system path like \"$ENV{PATH}\". "
" Note the double quotes around the ENV call TO_CMAKE_PATH only takes "
" one argument.\n"
"TO_NATIVE_PATH works just like TO_CMAKE_PATH, but will convert from "
" a cmake style path into the native path style \\ for windows and / "
"for UNIX.\n"
"DOWNLOAD will download the given URL to the given file. "
"If LOG var is specified a log of the download will be put in var. "
"If STATUS var is specified the status of the operation will"
" be put in var. The status is returned in a list of length 2. "
"The first element is the numeric return value for the operation, "
"and the second element is a string value for the error. A 0 "
"numeric error means no error in the operation. "
"If TIMEOUT time is specified, the operation will "
"timeout after time seconds, time can be specified as a float."
"\n"
"The file() command also provides COPY and INSTALL signatures:\n"
" file(<COPY|INSTALL> files... DESTINATION <dir>\n"
" [FILE_PERMISSIONS permissions...]\n"
" [DIRECTORY_PERMISSIONS permissions...]\n"
" [NO_SOURCE_PERMISSIONS] [USE_SOURCE_PERMISSIONS]\n"
" [FILES_MATCHING]\n"
" [[PATTERN <pattern> | REGEX <regex>]\n"
" [EXCLUDE] [PERMISSIONS permissions...]] [...])\n"
"The COPY signature copies files, directories, and symlinks to a "
"destination folder. "
"Relative input paths are evaluated with respect to the current "
"source directory, and a relative destination is evaluated with "
"respect to the current build directory. "
"Copying preserves input file timestamps, and optimizes out a file "
"if it exists at the destination with the same timestamp. "
"Copying preserves input permissions unless explicit permissions or "
"NO_SOURCE_PERMISSIONS are given (default is USE_SOURCE_PERMISSIONS). "
"See the install(DIRECTORY) command for documentation of permissions, "
"PATTERN, REGEX, and EXCLUDE options. "
"\n"
"The INSTALL signature differs slightly from COPY: "
"it prints status messages, and NO_SOURCE_PERMISSIONS is default. "
"Installation scripts generated by the install() command use this "
"signature (with some undocumented options for internal use)."
// Undocumented INSTALL options:
// - RENAME <name>
// - OPTIONAL
// - FILES keyword to re-enter files... list
// - PERMISSIONS before REGEX is alias for FILE_PERMISSIONS
// - DIR_PERMISSIONS is alias for DIRECTORY_PERMISSIONS
// - TYPE <FILE|DIRECTORY|EXECUTABLE|PROGRAM|
// STATIC_LIBRARY|SHARED_LIBRARY|MODULE>
// - COMPONENTS, CONFIGURATIONS, PROPERTIES (ignored for compat)
