[Boost-cmake] Building boost "with an uninstalled build" and linking to boost libs

I am currently trying the boost "With an uninstalled build" variety:

# Boost Related
SET( BOOST_LIB_INSTALL_DIR ${BUILD_DIR}/ouput/lib CACHE STRING "" FORCE )
SET( BOOST_EXPORTS_INSTALL_DIR ${BUILD_DIR}/ouput/lib CACHE STRING "" FORCE
)
SET( BOOST_INCLUDE_INSTALL_DIR ${BUILD_DIR}/ouput/include CACHE STRING ""
FORCE )
#SET( BUILD_PROJECTS NONE CACHE STRING "" FORCE )
SET( BUILD_PROJECTS thread filesystem CACHE STRING "" FORCE )

add_subdirectory( ${THIRD_PARTY_SRC_DIR}/boost-cmake-1_41_0 ./boost )

reading:
http://sodium.resophonic.com/boost-cmake/current-docs/exported_targets.htmlI
find:

--snip--
Example¶

There is an unpacked boost in /home/troy/boost-1.41.0/src and built boost in
directory /home/troy/boost/1.41.0/build. I have a program that builds from
one file, main.cpp and uses boost threads. My CMakeLists.txt looks like
this:

include_directories(
  /home/troy/boost-1.41.0/src
  /home/troy/boost-1.41.0/build/lib/Exports.cmake
  )

add_executable(my_program main.cpp)

target_link_libraries(my_program boost_thread-mt-shared-debug)

--end snip--

The part I don't like was the boost_thread-mt-shared-debug where
-share-debug needed to be specified.  What if I switch to release?

When I try to link some boost libs to a test app:

TARGET_LINK_LIBRARIES( ${SQUARE_ME_TEST_APP}
    ${MATLAB_CUDA_MEX_NAME}
    ${Boost_FILESYSTEM_LIBRARY}
    ${Boost_SYSTEM_LIBRARY}
#    boost_filesystem-mt-shared-debug
#    boost_filesystem
)

3>Linking...
3>LINK : fatal error LNK1104: cannot open file
'libboost_filesystem-vc90-mt-sgd-1_41.lib'

Now except for hte 'lib" preceeding
'libboost_filesystem-vc90-mt-sgd-1_41.lib' as only:

boost_filesystem-vc90-mt-sgd-1_41.lib
boost_filesystem-vc90-mt-gd-1_41.lib

are build on my Win64 system which I am sure is a result of
${Boost_FILESYSTEM_LIBRARY}

What is the best way to link to boost libs?  Except for the point  what did
I miss? :-)  I am sure it has something to do with (from
http://sodium.resophonic.com/boost-cmake/current-docs/exported_targets.html
):

-snip-
The problem here is that the real name of the multithreaded, shared, debug
library target is boost_thread-mt-shared-debug. I know this is confusing;
much of this is an attempt to be compatible with boost.build.

If you are having trouble, have a look inside that file Exports.cmake. For
each available target, you’ll see:

# Create imported target boost_thread-mt-shared-debug
ADD_LIBRARY(boost_thread-mt-shared-debug SHARED IMPORTED)

# Import target "boost_thread-mt-shared-debug" for configuration "Release"
SET_PROPERTY(TARGET boost_thread-mt-shared-debug APPEND PROPERTY
IMPORTED_CONFIGURATIONS RELEASE)
SET_TARGET_PROPERTIES(boost_thread-mt-shared-debug PROPERTIES
  IMPORTED_LINK_INTERFACE_LIBRARIES_RELEASE "pthread;rt"
  IMPORTED_LOCATION_RELEASE
"/home/troy/Projects/boost/cmake/cmaketest/build/boost/lib/libboost_thread-mt-d.so.1.41.0"
  IMPORTED_SONAME_RELEASE "libboost_thread-mt-d.so.1.41.0"
  )

it is the name in the ADD_LIBRARY line that you pass to
target_link_libraries().

-end snip-

my exports.cmake file (in trunk\build\dvip4-Win64\lib) shows:

-snip-
# Create imported target boost_thread-mt-shared
ADD_LIBRARY(boost_thread-mt-shared SHARED IMPORTED)

# Import target "boost_thread-mt-shared" for configuration "Debug"
SET_PROPERTY(TARGET boost_thread-mt-shared APPEND PROPERTY
IMPORTED_CONFIGURATIONS DEBUG)
SET_TARGET_PROPERTIES(boost_thread-mt-shared PROPERTIES
  IMPORTED_IMPLIB_DEBUG
"C:/projects/NIH2009/source/branches/trunk/build/dvip4-Win64/lib/Debug/boost_thread-vc90-mt-1_41.lib"
  IMPORTED_LOCATION_DEBUG
"C:/projects/NIH2009/source/branches/trunk/build/dvip4-Win64/bin/Debug/boost_thread-vc90-mt-1_41.dll"
  )

# Import target "boost_thread-mt-shared" for configuration "Release"
SET_PROPERTY(TARGET boost_thread-mt-shared APPEND PROPERTY
IMPORTED_CONFIGURATIONS RELEASE)
SET_TARGET_PROPERTIES(boost_thread-mt-shared PROPERTIES
  IMPORTED_IMPLIB_RELEASE
"C:/projects/NIH2009/source/branches/trunk/build/dvip4-Win64/lib/Release/boost_thread-vc90-mt-1_41.lib"
  IMPORTED_LOCATION_RELEASE
"C:/projects/NIH2009/source/branches/trunk/build/dvip4-Win64/bin/Release/boost_thread-vc90-mt-1_41.dll"
  )

-end snip-

but NO boost_filesystem which I presume has to do with:

SET( BUILD_PROJECTS thread filesystem CACHE STRING "" FORCE )

and the text:

-snip-
BUILD_PROJECTS¶

This is a semicolon-separated list of projects to be built, or "ALL" (the
default) for all projects, or "NONE". Projects not appearing in this list
(if list not "ALL") are ignored; no targets in this project will appear.
Example:

BUILD_PROJECTS=thread;python
-end snip-

I also tried

SET( BUILD_PROJECTS "thread;filesystem" CACHE STRING "" FORCE )

Do I need to even specify BUILD_PROJECTS or is there a way to specify the
dependency in either add_dependencies or in target_link_libraries?  This may
sound crazy, but a build system that supports a syntax of dependency
checking and building only what I need.  From what I can tell at the moment
with my current level of understanding of CMake... CMake really sucks at
this.  Let me be clear

SET(SQUARE_ME_TEST_APP squaremetest )
ADD_EXECUTABLE( ${SQUARE_ME_TEST_APP} square_me_test.cpp )

SET( BOOST_DEPS system filesystem  )

find_package( Boost REQUIRED COMPONENTS system filesystem  NO_MODULE )

MESSAGE( "Boost_FILESYSTEM_LIBRARY = " ${Boost_FILESYSTEM_LIBRARY} )

TARGET_LINK_LIBRARIES( ${SQUARE_ME_TEST_APP}
    ${MATLAB_CUDA_MEX_NAME}
    ${Boost_FILESYSTEM_LIBRARY}
    ${Boost_SYSTEM_LIBRARY}
#    boost_filesystem-mt-shared-debug
#    boost_filesystem
)

#ADD_DEPENDENCIES( ${SQUARE_ME_TEST_APP} boost-cmake-1_41_0 )
ADD_DEPENDENCIES( ${SQUARE_ME_TEST_APP} boost_filesystem )
