[CMake] add_custom_target dependency list issue

[Szilárd Páll]

Hi,

I implemented a custom target which depends on several other targets,
including some that I generate beforehand as custom targets and
collect their names in a variable. However, this seems to behave in a
strange way if I list these dependencies like this:

add_custom_target(foo COMMAND [...]
                                DEPENDS bar ${MORE_DEPENDENCIES}),

where ${MORE_DEPENDENCIES} contains space separated list of e.g "dep1 dep2 dep3"

The error I get with generated makefiles is:

make[3]: *** No rule to make target `path_to_bar/bar  dep1 dep2 dep3',
needed by [...] Stop.

The strange thing is that even if I explicitly list the dependency
names instead of passing them through the value of the
MORE_DEPENDECIES variable, I get an error that there is no rule to
make the respective target:

 make[3]: *** No rule to make target `dep1', needed by [...] Stop.

 What am I doing wrong? The custom targets dep1,2,3 are generated
right before "foo", and all of them seem to work (make dep1,2,3
succeeds).

Regards,
