[Cook] Foreach in a currentdirectory

[xancorreu]

Hi,

I have this cookfile:

all: algorisme.out hola.out;


algorisme.out: algorisme.cpp
{
     clang++ -o algorisme.out algorisme.cpp;
}

hola.out: hola.cpp
{
    clang++ -o hola.out hola.cpp;
}


I want to substitute this for the rule:

process every file with .cpp extension and write as this file.out

I try this:

%0.out: %.cpp
{
   clang...
}


but how to say that I want to process all the files in the current 
directory?
What should I add to all:?


Thanks in advance,
Xan.
