Question

我从CMake开始，使用Boost Python时遇到了以下问题。一个示例'hello world'程序需要boost和python库。在运行cmake之前，我创建了'build'目录，这就是我运行cmake的地方。我能够生成一个共享库并在该目录中使用它（使用python），但是当我输入make install并且我的库放在源目录中时，python无法读取它会引发错误：

ImportError：libboost_python.so.1.64.0：无法打开共享对象文件：没有这样的文件或目录

cmake_minimum_required( VERSION 2.8 )

project( test )
enable_language(CXX)

set( LIB_NAME pylib )

   include_directories(${Boost_INCLUDE_DIRS})
endif()

set_target_properties( ${LIB_NAME} PROPERTIES PREFIX "" )
