# If TARGET_PATH contains spaces then it is presumed to contain escaped spaces. GNU make
|

# has very limited support for paths containing spaces. $(wildcard) is the only function
|
||||
# that is aware of escaped spaces. However, $(wildcard) never returns paths with escaped
|
||||
# spaces !!! So if it e.g. finds in a path with 2 spaces 4 files then one ends up with a
|
||||
# return value consisting of 12 plain words :-((
|
||||
#
|
||||
# Fortunately we can work around that behaviour here because we know that the files we
|
||||
# are looking for have known extensions. So we can $(filter) the in our example above 12
|
||||
# words for file extensions so we come up with 4 path fragments. Then we remove those
|
||||
# path fragments with $(notdir) from the file names.
|
||||
#
|
||||
# So far so good. But here we want to process files from different paths in a single
|
||||
# recipe further down below and therefore want to prepend the paths to the files with
|
||||
# $(addprefix). However, $(foreach) isn't aware of escaped spaces (only $(wildcard) is).
|
||||
# Therefore, we need to replace the spaces with some other character temporarily in order
|
||||
# to have $(foreach) generate one invocation per file. We use the character '?' for that
|
||||
# purpose here, just because it is known to not be part of file names.
|
||||
#
|
||||
# Inside the recipe generated per file we then replace the '?' again with a space. As we
|
||||
# want to be compatible with cmd.exe for execution we're not using an escaped space but
|
||||
# rather double-quote the whole path.
|
||||
#
|
||||
# Note: The "strange" $(wildcard) further down below just serves the purpose to unescape
|
||||
# spaces for cmd.exe. This could have as well been done with another $(subst).
