I have a few things to say in response:
1) I was not aware of this
2) This is really useful, and I'm thrilled that it's there (it will
make my life a lot easier)
3) It still doesn't make me wrong. ;)

John,
If you have the "Header Search Paths" set for your target, then
the default project settings are ignored. If you get info on the
target, it has its own individual build settings. If the "Header
Search Paths" variable is bold, then it's set. You'll have to
click on it and then press the minus button to turn this off.
The project settings are not project-wide settings that apply to
all targets; they are default settings that can be overridden.
Ah, but there is a way to indiciate that you want to modify the
project level setting at the target level.
The macros "$(value)" (and yes, that's literally "value")
represents the previously define value of the build setting.
For example, if at the project level I set:
HEADER_SEARCH_PATHS = /foo/bar
and then at the target level I set
HEADER_SEARCH_PATHS = $(value) bar/baz
then when I build I get:
HEADER_SEARCH_PATHS = /foo/bar bar/baz
Note that the $(value) macros can go anywhere in the build setting
so I can just as easily prepend a search path or append and prepend
paths and so on.

Hi,
this morning I added a local include path into my XCode project
via the project info's build configuration. I found that the
#include lines I had were never being found.
I added
/usr/local/include/exiv2
into the
Header Search Paths
option for the entire project (i.e. click project icon, hit Apple-
I, click build tab, specify path for 'Header Search Paths').
when looking at the compiler output, these headers we're NOT
being included in the compilation. This is obviously why the
compiler was returning errors trying to include the files. But I
had thought this was the entire PURPOSE of the 'Header Search
Paths' option. I've checked this for both debug and release, to
ensure I wasn't deing silly and setting one config but then using
the other...
Then I changed the Header Search Paths for just the single
compilation unit, in this case a .mm file - and it works without
issues.
So why is XCode not using my additional 'Header Search Paths'
option, when I specify an additional dir at the project level
Has anyone else come across this?
