[Cmake] Build dir being a *subdir* of source?

[Schumacher, Gordon]

Is anyone out there running in a configuration where their build directory
is a subdirectory of their top-level source directory?

What I'd like to do is have my top-level project dir have, say "src",
"lib", "include", "doc", and "obj" as subdirectories within it.  The user
calls CMake within "obj", pointing it at the top-level dir.  (Obviously
there is no CMakeLists.txt in "obj".)

Is anyone running with such a configuration?  When I do this, CMake seems
to choke on the "make" step of a UNIX makefiles build on the first SUBDIRS
call:

make.exe[3]: Entering directory `j:/Max_LIB/obj/dos32/Debug/src'
Building dependencies. cmake.depends...
D:/progra~1/cmake-devel/bin/cmake.exe -SJ:/Max_Lib/src
-OJ:/Max_LIB/obj/dos32/Debug/src -HJ:/Max_Lib -BJ:/Max_LIB/obj/dos32/Debug
make.exe[3]: *** [cmake.depends] Error -1
make.exe[3]: Leaving directory `j:/Max_LIB/obj/dos32/Debug/src'
make.exe[2]: *** [default_target] Error 2
make.exe[2]: Leaving directory `j:/Max_LIB/obj/dos32/Debug/src'
make.exe[1]: *** [default_target_src] Error 2
make.exe[1]: Leaving directory `j:/Max_LIB/obj/dos32/Debug'
make.exe: *** [default_target] Error 2

It works okay if I build it from "J:/test" instead of
"j:/Max_LIB/obj/dos32/Debug", but an otherwise identical configuration.

The only thing that I'm doing "weird" that I can think of is this:
SET(EXECUTABLE_OUTPUT_PATH ${CMAKE_HOME_DIRECTORY}/bin/${TARGET} CACHE PATH
"Configure the executable output path.")
SET(LIBRARY_OUTPUT_PATH ${CMAKE_HOME_DIRECTORY}/lib/${TARGET} CACHE PATH
"Configure the library output path.")

Any thoughts?
