Linking errors when compiling Boost unit tests with CMake

I realize from the title that this may appear to be a duplicate, but none of the other posts' answers worked for me.

I get a ton of undefined reference errors when I try to compile my Boost unit tests using CMake 2.8

point3D_test.cpp

#define BOOST_TEST_MAIN
#define BOOST_TEST_MODULE "Point3D"
#include <boost/test/unit_test.hpp>

#include "point3D.h"

BOOST_AUTO_TEST_CASE(TestDefaultConstructor)
{
    Reprojection::Point3D pt;
    BOOST_CHECK_EQUAL(pt.X(), 0);
    BOOST_CHECK_EQUAL(pt.Y(), 0);
    BOOST_CHECK_EQUAL(pt.Z(), 0);
}

CMakeLists.txt

cmake_minimum_required(VERSION 2.8)
project(MyProject)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")

enable_testing()

# Necessary to automatically generate main() in tests
add_definitions(-DBOOST_TEST_DYN_LINK)

macro(BUILD_TEST TARGET_NAME SOURCES LIBRARIES)
    add_executable(${TARGET_NAME} ${SOURCES})
    target_link_libraries(${TARGET_NAME} ${LIBRARIES})
    add_test(${TARGET_NAME} ${TARGET_NAME})
endmacro(BUILD_TEST)

find_package(Boost COMPONENTS
    program_options
    filesystem
    system
    unit_test_framework
    REQUIRED)

set(MY_LIBS ${Boost_LIBRARIES})

BUILD_TEST(point3D_test point3D_test.cpp ${MY_LIBS})

This produces a bunch of errors like

CMakeFiles/point3D_test.dir/point3D_test.cpp.o: In function `init_unit_test()':

My unit test file is longer, but all of the errors are like this one. What's going on?
