Boost生成成功但无法生成makefile。我哪里做错了？

Question

尽管CMake已成功配置并使用Boost生成makefile，但我无法使用make命令为ARM处理器生成可执行文件，如下所示。

以下是我的配置设置：

1。）我在此链接中下载了在Raspberry Pi中编译的boost库1.49： http://www.raspberrypi.org/phpBB3/viewtopic.php?t=8111&p=195468

2。）文件层次结构如下：

sample-boost
   -> boost-stage (Contains the lib, and include directories of the boost taken from number 1)
   -> build (Contains the generated files from CMake)
   -> CMakeLists.txt
   -> main.cpp

注意：ARM交叉编译器完全正常工作，我已经交叉编译了一个hello world并使用CMake in Cygwin在Raspberry Pi中成功运行它（使用位于C：/cygwin/arm-pi.toolchain中的交叉工具链文件.cmake）。

1. 的main.cpp

   #include <iostream>
   #include <boost/thread.hpp>
   
   int main(){
   
   cout << "Hello" << endl;
   boost::this_thread::sleep(boost::posix_time::millisec(20));
   return 0;
   }
   

2. 的CMakeLists.txt

   cmake_minimum_required(VERSION 2.8)
   Project(main)
   SET(Boost_INCLUDE_DIR C:/Users/Emmett/Documents/EMMETT/sample-boost/boost-stage/include)
   SET(CMAKE_INCLUDE_PATH ${CMAKE_INCLUDE_PATH} "C:/Users/Emmett/Documents/EMMETT/sample-boost/boost-stage/include")
   SET(BOOST_ROOT C:/Users/Emmett/Documents/EMMETT/sample-boost/boost-stage)
   
   FIND_PACKAGE(Boost)
   
   message("BOOST LIBRARY" ${Boost_LIBRARY_DIRS})
   message("Boost LIBRARIES:" ${Boost_LIBRARIES})
   
   
   IF(Boost_FOUND)  
   message("Boost include directory is found")
   message("Boost_INCLUDE_DIRS": ${Boost_INCLUDE_DIRS})
   include_directories(${Boost_INCLUDE_DIRS})
   add_executable(main main.cpp)
   target_link_libraries( main ${Boost_LIBRARIES} )
   ENDIF(Boost_FOUND)
   

3. 升压级   - ＆GT; include（来自sample-boost \ boost_1_49_0 \ boost）



  -> lib (came from boost_1_49_0(bin-only)\lib



另外，调用ccmake。显示找不到boost_dir。但是，发现了升级包！



如您所见，它已成功使用CMake生成makefile，但我无法为其创建可执行文件。我想我错过了设置提升的东西。也许我没能成功链接这些库？

    message("Boost LIBRARIES:" ${Boost_LIBRARIES})

显示库文件？

补充：我做了你要求的。这是我的新cmakelists.txt

cmake_minimum_required(VERSION 2.8)
Project(main)
SET(Boost_INCLUDE_DIR C:/Users/Emmett/Documents/EMMETT/sample-boost/boost-stage/include)
SET(CMAKE_INCLUDE_PATH ${CMAKE_INCLUDE_PATH} "C:/Users/Emmett/Documents/EMMETT/sample-boost/boost-stage/include")
SET(BOOST_ROOT C:/Users/Emmett/Documents/EMMETT/sample-boost/boost-stage)
SET(Boost_USE_STATIC_LIBS TRUE)
SET(Boost_DEBUG ON)
#FIND_PACKAGE(Boost)
FIND_PACKAGE(Boost COMPONENTS thread)

message("BOOST LIBRARY: " ${Boost_LIBRARY_DIRS})
message("Boost LIBRARIES: " ${Boost_LIBRARIES})
message("LIBS : " ${LIBS})

IF(Boost_FOUND)
    message("Boost include directory is found")
    message("Boost_INCLUDE_DIRS: "${Boost_INCLUDE_DIRS})
    include_directories(${Boost_INCLUDE_DIRS})
    add_executable(main main.cpp)
    target_link_libraries( main ${Boost_LIBRARIES} )
ENDIF(Boost_FOUND)

这是输出控制台：

要将增强螺纹模块与CMake配合使用，必须执行

find(Boost COMPONENTS thread)

Normaly，这会在Boost_LIBRARIES var。

中添加boost线程lib的路径
