[Cmake] why does clean depend on external targets?

[Jan Woetzel]

Hi,
my cmake project MIP depend on a second cmake project BIAS through 
"BIASConfig.cmake" using the CMakeImportBuildSettings.cmake macro.
This is correct for compiling.

But the problem is that the clean target of MIP also depends on BIAS 
through "cmake.depends".
The result is that I cannot clean MIP if BIAS has been removed.

(1) How can I separate dependencies from a 'clean' target ?

I am using cmake 2.1.0 with make on linux:
