CMake與Boost庫的鏈接

Question

我正在嘗試與Windows CMake項目的boost_system庫鏈接，但始終收到以下錯誤。 我已經針對類似的問題嘗試了幾種建議的解決方案，但似乎無濟於事。

Error:Unable to find the requested Boost libraries.
Boost version: 1.60.0
Boost include path: C:/Program Files/boost_1_60_0
Could not find the following Boost libraries:
    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.

這是我的cmake文件的當前狀態（與boost有關）

set(Boost_USE_STATIC_LIBS OFF)  
set(Boost_USE_MULTITHREADED ON)
set(Boost_USE_STATIC_RUNTIME OFF)

SET(BOOST_INCLUDEDIRS "C:/Program Files/boost_1_60_0")
SET(BOOST_LIBRARYDIR "C:/Program Files/boost_1_60_0/lib")

find_package(Boost 1.60.0 COMPONENTS system REQUIRED)

if(Boost_FOUND)
    include_directories(${Boost_INCLUDE_DIRS})
LINK_DIRECTORIES(${Boost_LIBRARY_DIRS})
endif()

Answer 1

這是我可移植使用的方式，但是您需要指定所需的組件：

首先，您需要構建庫。 在Windows中打開命令提示符並鍵入以下內容：（您需要指定MinGW安裝文件夾的/ bin /文件夾，因此請相應地修改第一行）

PATH=C:\MinGW\bin;%PATH%
cd C:/Program Files/boost_1_60_0/
bootstrap.bat 
b2 --toolset=gcc link=static --build-type=complete

編譯需要花費幾分鍾。 然后在您的CMakeLists.txt中添加：

if (WIN32)
    set(BOOST_ROOT C:/Program Files/boost_1_60_0/)
    set(Boost_USE_STATIC_LIBS OFF)  
    set(Boost_USE_MULTITHREADED ON)
    set(Boost_USE_STATIC_RUNTIME OFF)

    include_directories(${BOOST_ROOT})
    link_directories(${BOOST_ROOT}/stage/lib) # add this before add_executable()
endif()

# Here add your add_executable function
add_executable(your_exec ${SOURCE_FILES} ${INCLUDE_FILES})

if(NOT MSVC)
    find_package(Boost REQUIRED COMPONENTS date_time filesystem wserialization system serialization thread regex)

    if (Boost_FOUND)
        include_directories(${Boost_INCLUDE_DIRS})
        target_link_libraries(your_exec ${Boost_LIBRARIES})
    endif()
endif()

Answer 2

您使用了錯誤的變量名。 它應該是

SET(BOOST_INCLUDEDIR "C:/Program Files/boost_1_60_0")

注意缺失的復數-s。 另請參閱https://cmake.org/cmake/help/v3.5/module/FindBoost.html

順便說一句，您不應該這樣設置，而是將C:/Program Files/boost_1_60_0到CMAKE_PREFIX_PATH並將其傳遞給cmake調用。
