I was able to reproduce my problem with cmake as well as ccmake:
$ cmake -G"Unix Makefiles" ..
-- The C compiler identification is GNU
-- The CXX compiler identification is GNU
-- Check for working C compiler: /usr/bin/gcc
-- Check for working C compiler: /usr/bin/gcc -- works
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - done
-- Check for working CXX compiler: /usr/bin/c++
-- Check for working CXX compiler: /usr/bin/c++ -- works
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
-- Configuring done
CMake Error in CMakeLists.txt:
  Cannot find source file "foo.cc".  Tried extensions .c .C .c++ .cc .cpp
  .cxx .m .M .mm .h .hh .h++ .hm .hpp .hxx .in .txx


Assertion failed: (!relFromSource.empty()), function
GetObjectFileNameWithoutTarget, file

Abort trap

I'm using ccmake version 2.6.0 I got from mac ports (running on Mac 10.5.2).

$ ccmake --version
ccmake version 2.6-patch 0

Have you tried using this version of cmake?
