Hello,
The following is in boost "getting started" documentation:
Auto-Linking
Most Windows compilers and linkers have so-called
“auto-linking support,” which eliminates the second
challenge. Special code in Boost header files detects your
compiler options and uses that information to encode the
name of the correct library into your object files; the
linker selects the library with that name from the
directories you've told it to search.
when you build your visual studio boost project created
with cmake, libboost_filesystem-vc-mt-sgd-1_41.lib is
created instead of
libboost_filesystem-vc90-mt-sgd-1_41.lib. (see
boostBuild/lib) directory.
Now when you try to build a project that use boost,
because of the special code in boost header files, visual
studio will try to find
libboost_filesystem-vc90-mt-sgd-1_41.lib instead of
libboost_filesystem-vc-mt-sgd-1_41.lib
so I think that boost-cmake is not naming the libs
correctly for visual studio.

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

SET_PROPERTY(TARGET boost_thread-mt-shared APPEND

)
-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
