[CMake] "Command line too long" under Windows

[Martin Apel]

Hi all,

I am currently in the process of trying to convert the build system of
our software to CMake.
Unfortunately there is one static library consisting of lots of objects
(about 5700), which has lots of cyclic references, so I cannot easily
split it up.
I can generate this large library on Linux without problems. When trying
to do the same under Windows, the build fails, because the link line is too
long:
  "CMakeFiles/spck.dir/objects.rsp : fatal error LNK1170: line in
command file contains 131071 or more characters"

An inspection of the file shows a single line with about 300.000
characters. Is there any way to work around this problem besides
splitting up
the library? The CMake version I am using is 2.6.2 and I have tried with
both the Visual Studio 8 generator (nmake) and the Unix makefile generator,
but the problem shows up with both approaches.

Regards,

Martin
