feat(build): add_glob_target runs only on changed files #19070
The general idea is that add_glob_targets creates a "touch file", a dummy file that acts as a dependency in order to check which files are outdated since the last time the target was run. Remove RunUncrustify.cmake as it's no longer necessary. It was initially introduced to silence its noisy output. The per-file targets will suppress the noisy output from uncrustify, except for the very first run. Also remove DefCmdTarget.cmake since add_glob_target already incorporates its functionality.

# Defines a target that depends on FILES and the files found by globbing
|
||||
# when using GLOB_PAT and GLOB_DIRS. The target will rerun if any files it
|
||||
# depends on has changed. Which files the target will run the command on
|
||||
# depends on the value of TOUCH_STRATEGY.
|
||||
#
|
||||
# Options:
|
||||
# REQUIRED - Abort if COMMAND doesn't exist.
|
||||
#
|
||||
# Single value arguments:
|
||||
# TARGET - Name of the target
|
||||
# COMMAND - Path of the command to be run
|
||||
# GLOB_PAT - Glob pattern to use. Only used if GLOB_DIRS is specified
|
||||
# TOUCH_STRATEGY - Specify touch strategy, meaning decide how to group files
|
||||
# and connect them to a specific touch file.
|
||||
#
|
||||
# For example, let us say we have file A and B and that we create a touch file
|
||||
# for each of them, TA and TB. This would essentially make file A and B
|
||||
# independent of each other, meaning that if I change file A and run the
|
||||
# target, then the target will only run its commands for file A and ignore
|
||||
# file B.
|
||||
#
|
||||
# Another example: let's say we have file A and B, but now we create only a
|
||||
# single touch file T for both of them. This would mean that if I change
|
||||
# either file A or B, then the target will run its commands on both A and B.
|
||||
# Meaning that even if I only change file A, the target will still run
|
||||
# commands on both A and B.
|
||||
#
|
||||
# The more touch files we create for a target, the fewer commands we'll need
|
||||
# to rerun, and by extension, the more time we'll save. Unfortunately, the
|
||||
# more touch files we create the more intermediary targets will be created,
|
||||
# one for each touch file. This makes listing all targets with
|
||||
# `cmake --build build --target help` less useful since each touch file will
|
||||
# be listed. The tradeoff that needs to be done here is between performance
|
||||
# and "discoverability". As a general guideline: the more popular a target is
|
||||
# and the more time it takes to run it, the more granular you want your touch
|
||||
# files to be. Conversely, if a target rarely needs to be run or if it's fast,
|
||||
# then you should create fewer targets.
|
||||
#
|
||||
# Possible values for TOUCH_STRATEGY:
|
||||
# "SINGLE": create a single touch file for all files.
|
||||
# "PER_FILE": create a touch file for each file. Defaults to this if
|
||||
# TOUCH_STRATEGY isn't specified.
|
||||
# "PER_DIR": create a touch file for each directory.
|
||||
#
|
||||
# List arguments:
|
||||
# FLAGS - List of flags to use after COMMAND
|
||||
# FILES - List of files to use COMMAND on. It's possible to combine this
|
||||
# with GLOB_PAT and GLOB_DIRS; the files found by globbing will
|
||||
# simple be added to FILES
|
||||
# GLOB_DIRS - The directories to recursively search for files with extension
|
||||
# GLOB_PAT
