Clean out your build folder first.
export BOOST_ROOT=/home/kknox/sdk/boost_1_44_0
==> that needs to be an actual "installation", a staged area will
probably NOT work to find boost as FindBoost is looking for a very
specific path within BOOST_ROOT and if that path is NOT found then it
will probably fall back on the system paths.
Also.
put the following in your CMakeLists.txt file after you try to find
boost:
message(STATUS "Boost_PROGRAM_OPTIONS_LIBRARY: $
{Boost_PROGRAM_OPTIONS_LIBRARY}")
You should get the absolute path to the boost program_options library.
For example is a project I have I get the following:
Boost_THREAD_LIBRARY /Users/Shared/Toolkits/MXABoost-1.44/
lib/libboost_thread-mt.a
Boost_THREAD_LIBRARY_DEBUG /Users/Shared/Toolkits/MXABoost-1.44/
lib/libboost_thread-mt-d.a
Boost_THREAD_LIBRARY_RELEASE /Users/Shared/Toolkits/MXABoost-1.44/
lib/libboost_thread-mt.a
where my BOOST_ROOT=/Users/Shared/Toolkits/MXABoost-1.44

Are you sure this logic is right? It looks very odd. Does CMake set
WIN32 for a 64-bit Windows toolchain? Didn't you say you were
building on Linux?
[Kent]
My software compiles cross platform, and we support windows too.
WIN32 is set for 64bit platforms. I do have the windows build
compiling properly with boost. I'm specifically having problems
with linux.

You don't set ADDITIONAL_VERSIONS. That's probably not the problem.
IIRC, it's:
set(Boost_ADDITIONAL_VERSIONS "1.44 1.44.0")
[Kent]
I did not originally set Boost_ADDITIONAL_VERSIONS. I did set it
now, and ran a clean recompile, but no change. My Boost_LIBRARIES
still came out as:
-- Boost_LIBRARIES: /usr/lib/libboost_program_options-mt.a
Even though I've specified BOOST_LIBRARYDIR as:
BOOST_LIBRARYDIR = /home/kknox/sdk/boost_1_44_0/stage/lib

Hi all~
Hi Kent.
I have a project using Boost that should compile for both 64bit and
32bit on a 64bit host. This works fine for a 64bit target, but I
can't get this to work for a 32bit target.
I'm having problems linking Boost too. But enough about me.
In order to compile for 32bit on a 64bit host, I have a -D parameter
called BUILD64. Here is my logic to initialize this var:
if( WIN32 )
set( BUILD64 ${CMAKE_CL_64} )
else()
option( BUILD64 "Build a 64-bit product" OFF )
if( BUILD64 )
message( STATUS "64-bit build" )
endif( )
endif()
Are you sure this logic is right? It looks very odd. Does CMake set
WIN32 for a 64-bit Windows toolchain? Didn't you say you were
building on Linux?
The syntax for finding boost is thus:
set( Boost_USE_MULTITHREADED ON )
set( Boost_USE_STATIC_LIBS ON )
set( Boost_DETAILED_FAILURE_MSG ON )
# set( Boost_DEBUG ON )
find_package( Boost 1.33.0 COMPONENTS program_options )
You don't set ADDITIONAL_VERSIONS. That's probably not the problem.
IIRC, it's:
set(Boost_ADDITIONAL_VERSIONS "1.44 1.44.0")
... if you wanted to try it anyway.
