c++ - CMake is not finding Boost

Question

I am trying to install CGAL. They describe their installation process as ever-so-simple here, section 6.1. When I run cmake-gui and then click configure, I get the following output:

CMake Error at D:/program files/CMake 2.8/share/cmake-2.8/Modules/FindBoost.cmake:1192 (message):
  Unable to find the requested Boost libraries.

  Boost version: 1.51.0

  Boost include path: D:/program files/boost_1_51

  The following Boost libraries could not be found:

          boost_thread
          boost_system

  No Boost libraries were found.  You may need to set BOOST_LIBRARYDIR to the
  directory containing Boost libraries or BOOST_ROOT to the location of
  Boost.
Call Stack (most recent call first):
  cmake/modules/CGAL_SetupBoost.cmake:6 (find_package)
  cmake/modules/CGAL_SetupDependencies.cmake:85 (include)
  CMakeLists.txt:590 (include)

But I did set up BOOST_ROOT, in CMake's GUI, to D:/program files/boost_1_51, which exists. And the two libraries it mentions are definitely installed. What is happening here? What do I need to do?

Attached is the output when running cmake -DBoost_DEBUG=ON:

_{(I saw at least three questions with the same title as this question. Each of them had a different answer that worked for the OP, but not for me, so I am sorry to repeat the question...)}

Answer 1

Your output shows that CMake is searching for the libraries in the following places:

D:/program files/boost_1_51/bin/lib
D:/program files/boost_1_51/bin/stage/lib
D:/program files/boost_1_51/lib
D:/program files/boost_1_51/../lib
D:/program files/boost_1_51/stage/lib
C:/boost/lib
C:/boost
C:Program Files (x86)/boost/boost_1_51_0/lib
C:Program Files (x86)/boost/boost_1_51/lib
C:Program Files (x86)/boost/lib
C:Program Files (x86)/boost
/sw/local/lib

It also shows that it's expecting the libraries to be named in a certain way. For example, the release version of Boost.Thread:

boost_thread-vc100-mt-1_51
boost_thread-vc100-mt
boost_thread-mt-1_51
boost_thread-mt
boost_thread

If your Boost libraries do exist in one of the searched locations, then it's probably the name of the library that's the problem. You can adjust the expected name of the Boost libraries by setting the appropriate CMake variables relevant to the FindBoost module.

For example, if you built Boost using bjam with link=static threading=multi then in your CMakeLists.txt before find_package(Boost ...) you'll want to do

set(Boost_USE_STATIC_LIBS ON)
set(Boost_USE_MULTITHREADED ON)

Or invoke CMake with -DBoost_USE_STATIC_LIBS=ON -DBoost_USE_MULTITHREADED=ON.

As @noam has pointed out in the comments below, in this particular case, it appears that CGAL requires the shared (DLL) versions of the Boost libraries; passing -DBoost_USE_STATIC_LIBS=ON on the command line doesn't have any effect.
