[Cmake] why cmake is so slow on AIX 5.2

[David Wallman]

We do our builds on Solaris and AIX. We use ant as a top level build =
tool.
Performance of java, ant, compiler and make is comparable on both =
systems, but not CMake.
It turned out our build on AIX spends about 95% of time doing something =
like the following :=20

     [exec] Building dependencies. cmake.depends...
     [exec] /home/davidwa/AIX/bin/cmake =
-S/home/davidwa/shared/p4/P2/openkernel/main/cpp/src/transformers =
-O/home/davidwa/shared/p4/P2/openkernel/main/cpp/build/AIX/src/transforme=
rs -H/home/davidwa/shared/p4/P2/openkernel/main/cpp =
-B/home/davidwa/shared/p4/P2/openkernel/main/cpp/build/AIX

Does anybody knows why it is so slow?=20
