Re: spaces...

[address@hidden]

Thank you for your quick and precise answer.
Actually we can use the shell function "if exist".
I'm sorry because I have made an error in my tests, I have found my error in testing your 
solution... So we can use wildcard function with spaces, we must only use "\ " 
(without quotes) for real-spaces.

# So my function EXIST :
EXIST=$(wildcard $(subst $(SPACE_FAKE),\ ,$(1)))

# you can use this function like this :
$(call EXIST,                                                                   
                       \
        
path/to/file$(SPACE_FAKE)or$(SPACE_FAKE)directory$(SPACE_FAKE)with$(SPACE_FAKE)spaces/file.exe
 \
        another/file/path.exe                                                   
                       \
)

You must only define $(SPACE_FAKE) like you want (or use directly "\ " always).
The idea is to replace the spaces in an environment variable, like in $(PATH), by 
$(SPACE_FAKE) and the ";" by spaces. And so you can work with spaces easily.

The function wildcard can work with / or \ for the path.

The function wildcard allows you to tests many files at the same time and it 
returns the list of founded files.

Another remark :
In my makefile, I test where can be my library files, so I test many possible path. With 
wildcard function, it takes 5 seconds and with a call to the shell function "if 
exist", it takes more than 3 minutes !
