[CMake] custom targets can't be used in different subdirectories?

[Gaëtan Lehmann]

Hi,

I'm currently trying to build a project organized in subdirectories.  
In all the subdirectories, several files are generated at build time  
(with an ADD_CUSTOM_COMMAND).
In all the directories, a custom target depending on all the files  
generated in the subdirectory is created with ADD_CUSTOM_TARGET, so  
it should be easy to declare a dependancy on all those files in  
another subdirectory.

During the build, things are all right until "make" try to build a  
file which depends on a custom target from another subdirectory. Here  
is an example:

[glehmann at marvin build]$ LC_ALL=C make BaseSwig
[  0%] Built target VXLNumericsIdx
make[3]: *** No rule to make target `VXLNumericsIdx', needed by  
`ClassIndex/wrap_ITKCommonBase.i'.  Stop.
make[2]: *** [Modules/Base/CMakeFiles/BaseSwig.dir/all] Error 2
make[1]: *** [Modules/Base/CMakeFiles/BaseSwig.dir/rule] Error 2
make: *** [BaseSwig] Error 2

VXLNumericsIdx is defined in one subdir, and BaseSwig in another on.  
"make" reports that the custom target "VXLNumericsIdx" is built  
(that's true), but the line after, it say it can't find that target.
It seems definitively strange to me!

I'm using cmake cvs 2007-10-24, and have seen the same behavior with  
cmake 2.4.5

Any idea about what can be wrong?

Thanks,

Gaëtan
