Boost "undefined reference" errors even with -lboost_thread - c++

Question

I'm getting some strange compiler/linker errors when trying to use boost::shared_mutex. I'm using boost v1.61 on a VM running 32-bit rhel 6.2.
Code that causes error:
hpp file:
#include <boost/thread/shared_mutex.hpp>
class SharedData
{
public:
SharedData();
~SharedData();
void packMessage(std::shared_ptr<Message> s);
private:
// mutex that allows multiple read, single write protection
boost::shared_mutex m_sharedMutex;
};
cpp file:
void SharedData::packMessage(std::shared_ptr<Message> s)
{
// get shared read access
boost::shared_lock<boost::shared_mutex> lock(m_sharedMutex); // <- this line causes the errors
// read stuff here
}
make output:
CMakeFiles/tester.dir/__/src/SharedData/SharedData.cpp.o: In function `boost::detail::interruption_checker::interruption_checker(pthread_mutex_t*, pthread_cond_t*)':
/usr/local/include/boost/thread/pthread/thread_data.hpp:195: undefined reference to `boost::detail::get_current_thread_data()'

collect2: error: ld returned 1 exit status
make[2]: *** [bin/tester] Error 1
Everywhere I've searched has said that these errors mean I need to link the boost_thread library, which I've done in my cmake file (boost_system is included for other code in this same project):
target_link_libraries(${BINARY_NAME} boost_thread boost_system)
But the errors persist.
Originally I was using the boost 1.41 libraries that were already installed on my machine. When I hit these errors I ran yum remove boost-devel and then manually installed boost 1.61 to see if that would correct the errors. Is there something extra I needed to add to the ./bootstrap.sh or ./b2 install commands? I can see libboost_thread.a in /usr/local/lib, so I assumed that meant the thread library was built correctly.
Any thoughts on what is causing these errors? Thanks!
Edit:
Cmake's log didn't have anything useful I could see, but make VERBOSE=1 gives the following output:

Turns out my question is just like everyone else's.
#jww suggested I show the actual compile and link command invocation, not CMake's output, which I've added to my question. As you can see, the command is linking boost_system and pthread, but not boost_thread.
Digging into my project I realized that I had added boost_thread to my release build, but not into my unit test build, which is what I was trying to compile. Adding boost_thread to the unit test's CMakeLists.txt removed the error immediately.
