Put this in your <code>CMakeLists.txt</code> file (change any options from OFF to ON if you want):

<pre><code>set(Boost_USE_STATIC_LIBS OFF) 
set(Boost_USE_MULTITHREADED ON) 
set(Boost_USE_STATIC_RUNTIME OFF) 
find_package(Boost 1.45.0 COMPONENTS *boost libraries here*) 

if(Boost_FOUND)
 include_directories(${Boost_INCLUDE_DIRS}) 
 add_executable(progname file1.cxx file2.cxx) 
 target_link_libraries(progname ${Boost_LIBRARIES})
endif()
</code></pre>

Obviously you need to put the libraries you want where I put <code>*boost libraries here*</code>. For example, if you're using the <code>filesystem</code> and <code>regex</code> library you'd write:

<pre><code>find_package(Boost 1.45.0 COMPONENTS filesystem regex)
</code></pre>

blocks|key|842282|text|我同意1和2的回答。但是，我更喜欢分别指定每个库。这使得大型项目中的依赖关系更加清晰。然而，存在错误键入(区分大小写的)变量名的危险。在这种情况下，没有直接的cmake错误，但稍后会出现一些未定义的引用链接器问题，这可能需要一些时间才能解决。因此，我使用以下cmake函数：|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|842283|function(VerifyVarDefined)

I agree with the answers <a href="https://stackoverflow.com/a/6646518/5525302">1</a> and <a href="https://stackoverflow.com/a/6646746/5525302">2</a>. However, I prefer to specify each library separately. This makes the depencencies clearer in big projects.
Yet, there is the danger of mistyping the (case-sensitive) variable names.
In that case there is no direct cmake error but some undefined references linker issues later on, which may take some time to resolve. Therefore I use the following cmake function:

<pre><code>function(VerifyVarDefined)
 foreach(lib ${ARGV}) 
 if(DEFINED ${lib})
 else(DEFINED ${lib})
 message(SEND_ERROR "Variable ${lib} is not defined")
 endif(DEFINED ${lib})
 endforeach()
endfunction(VerifyVarDefined)
</code></pre>

For the example mentioned above, this looks like:

<pre><code>VerifyVarDefined(Boost_PROGRAM_OPTIONS_LIBRARY Boost_REGEX_LIBRARY)
target_link_libraries( run ${Boost_PROGRAM_OPTIONS_LIBRARY} ${Boost_REGEX_LIBRARY} )
</code></pre>

If I had written "BOOST_PROGRAM_OPTIONS_LIBRARY" there would have been an error triggered by cmake and not much later triggered by the linker.

Adapting @LainIwakura's answer for modern CMake syntax with imported targets, this would be:

<pre><code>set(Boost_USE_STATIC_LIBS OFF) 
set(Boost_USE_MULTITHREADED ON) 
set(Boost_USE_STATIC_RUNTIME OFF) 
find_package(Boost 1.45.0 COMPONENTS filesystem regex) 

if(Boost_FOUND)
 add_executable(progname file1.cxx file2.cxx) 
 target_link_libraries(progname Boost::filesystem Boost::regex)
endif()
</code></pre>

Note that it is not necessary anymore to specify the include directories manually, since it is already taken care of through the imported targets <code>Boost::filesystem</code> and <code>Boost::regex</code>. 
<code>regex</code> and <code>filesystem</code> can be replaced by any boost libraries you need.

If you are using custome boost path, set <code>CMAKE_PREFIX_PATH</code> firstly. So, cmake can find your custome boost.
<pre><code>list(FIND CMAKE_PREFIX_PATH ${CUSTOME_BOOST_DEP_PREFIX} _INDEX)
if (_INDEX EQUAL -1)
 list(APPEND CMAKE_PREFIX_PATH ${CUSTOME_BOOST_DEP_PREFIX})
 # set(CMAKE_PREFIX_PATH ${CMAKE_PREFIX_PATH} PARENT_SCOPE)
endif ()
</code></pre>
By the way, if you run above code in sub cmake file, should set <code>CMAKE_PREFIX_PATH</code> back to parent scope.
<pre><code>set(CMAKE_PREFIX_PATH ${CMAKE_PREFIX_PATH} PARENT_SCOPE)
</code></pre>
If you want find all components of boost, using below code.
<pre><code>find_package(Boost 1.76 COMPONENTS ALL)
</code></pre>
