Short answer: use the [quote] function.


Longer explanation, with examples...

I created an example cookbook like this

        all: fred;
        
        src = [glob *.c];
        obj = [fromto %.c %.o [src]];
        
        fred: [obj]
        {
            gcc -o [target] [obj];
        }
        
        %.o: %.c
        {
            gcc -O2 -c %.c -o [target];
        }

and then I created two source files: main.c and ab'cd.c
this, predictably, had problems...

        cook: gcc -O2 -c main.c -o main.o
        cook: gcc -O2 -c ab'cd.c -o ab'cd.o
        gcc: abcd.c -o abcd.o: No such file or directory
        gcc: no input files
        cook: command gcc: exit status 1
        cook: all: not done because of errors

Cook handles quotes in file names just fine (they are simply strings,
after all), and as you can see it found ab'cd.c and worked out it needed
ab'cd.o just fine.  The wheels can off when it needed to run a shell
command with quotes in it.

The [quote] function (see the user manual) was designed for just this
purpose.  Cook doesn't automagically quote everything, because there are
equally valid times when you *don't* want things quoted.  So its up to
the cookbook writer to say what they mean.

If strategic portions of the cookbook employ the [quote] function, like
this

        all: fred;
        
        src = [glob *.c];
        obj = [fromto %.c %.o [src]];
        
        fred: [obj]
        {
            gcc -o [quote [target]] [quote [obj]];
        }
        
        %.o: %.c
        {
            gcc -O2 -c [quote %.c] -o [quote [target]];
        }

then everything works as expected

        cook: gcc -O2 -c main.c -o main.o
        cook: gcc -O2 -c "ab'cd.c" -o "ab'cd.o"
        cook: gcc -o fred "ab'cd.o" main.o

hope this helps
