Disabling a Visual Studio project for building using cmake

Question

I'm generating a VS2010 solution with a few projects (currently 4, will be up to 10-20 in the end). I only want one of them to build; the rest should be disabled. I can do this manually by going into the configuration manager and unchecking the boxes I don't want, but obviously this isn't a good solution.

Is there something I can add to the CMakeLists.txt file for a project that will cause it to do this? Searching through the docs, google and SO yielded nothing.

Update: Here is my root CMakeLists.txt in case that helps:

cmake_minimum_required(VERSION 2.8)

add_definitions(-DCOMPILER_MSVC)
project (PDEngine)

set(LINKER_LANGUAGE CXX)

add_subdirectory (units/platform)
add_subdirectory (units/render_api)
add_subdirectory (units/memory)
add_subdirectory (units/game)

set(custom_exe "${CMAKE_CURRENT_BINARY_DIR}/units/Platform/Debug/Platform.lib2")

add_custom_command(OUTPUT ${custom_exe}
  COMMAND ${CMAKE_CURRENT_SOURCE_DIR}/local/msvc/bam.bat -j $ENV{NUMBER_OF_PROCESSORS}
  DEPENDS ${CMAKE_CURRENT_SOURCE_DIR}/local/msvc/bam.bat
)
#add_custom_command(OUTPUT ${custom_exe_clean}
  #COMMAND ${CMAKE_CURRENT_SOURCE_DIR}/local/msvc/bam.bat -c
  #DEPENDS ${CMAKE_CURRENT_SOURCE_DIR}/local/msvc/bam.bat
#)

add_custom_target(bam ALL DEPENDS ${custom_exe})
#add_custom_target(bamclean ALL DEPENDS ${custom_exe_clean}})

(The bam.bat stuff is based off of the answer I got here: How do I configure CMake to make the VS solution use a specific build commandline? )

And here's the CMakeLists.txt for the "platform" project:

cmake_minimum_required (VERSION 2.8)
project (Platform)

set (COMPILER_MSVC 1)

include_directories(${Platform_SOURCE_DIR}/include)
file(GLOB Project_HEADERS ${Platform_SOURCE_DIR}/include/platform/*.h)
source_group("Headers" FILES ${Project_HEADERS})

add_library(Platform STATIC EXCLUDE_FROM_ALL src/*.cpp ${Project_HEADERS})

So if what you want to do is not build something by default, you can remove it from the "ALL" target (which shows up in Visual Studio as ALL_BUILD). The way you do this is with the target property EXCLUDE_FROM_ALL, or by passing EXCLUDE_FROM_ALL to add_executable and add_library. (Custom targets default to EXCLUDE_FROM_ALL, so there, to do the reverse, you add ALL to the arguments to add_custom_target).

Then, all your targets will show up, but when clicking "build solution", only the ones you want will build. Others can be built by right clicking them and choosing "Build", like the built-in INSTALL project/target.
