[CMake] Intermediate directory

[gekso]

Hi! I use VS2010 generator. When I'm setting
set_target_properties (${target} PROPERTIES RUNTIME_OUTPUT_DIRECTORY
${CMAKE_BINARY_DIR}/__bin/${CMAKE_BUILD_TYPE}

I have in output project file such lines:
     <OutDir Condition="'$(Configuration)|$(Platform)'=='release|Win32'">__bin\release\</OutDir>
     <IntDir Condition="'$(Configuration)|$(Platform)'=='release|Win32'">target.dir\release\</IntDir>

How I can change path to IntDir? I need to set something like "_obj\release"...
Thanks!
