[CMake] Problem getting out-of-source builds (yes I deleted CMakeCache.txt)

[Convey, Christian J CIV NUWC NWPT]

Hi guys,

Does anyone know why I might be having trouble getting out-of-source builds?

I have this directory structure:

foo
   /build
   /src
       /CMakeLists.txt
       /library_A
                 /CMakeLists.txt
                 /a.cpp
                 ...
       /library_B
                 /CMakeLists.txt
                 /b.cpp
                 ...

My goal is to have this work:
   > cd foo/build
   > cmake ../src/CMakeLists.txt
   > make

But my problems is that when I invoke 'cmake' as shown above, it places the build files under 'foo/src/', rather than under 'foo/build/'.

I'm absolutely positive that the file 'foo/src/CMakeCache.txt' does not exist when I invoke cmake.  I'm running CMake 2.6.2.

Any ideas?
