我有一个使用Boost和Qt的项目，并使用CMake编译。当我使用cmake … -DCMAKE_RELEASE_TYPE=Release -G ninja构建它并使用ninja构建它时，它可以正常工作。

要进行UI和调试，我想使用Qt Creator。当我用它打开CMake项目时，它找不到Boost：

CMake Error at /usr/share/cmake-3.0/Modules/FindBoost.cmake:1199 (message):
  Unable to find the requested Boost libraries.

  Boost version: 1.55.0

  Boost include path: /usr/include

  Could not find the following Boost libraries:

          boost_filesystem
          boost_system
          boost_serialization

  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):
  CMakeLists.txt:17 (find_package)
-- Configuring incomplete, errors occurred!
See also "…/CMakeOutput.log".
See also "…/CMakeError.log".

顶级CMakeLists.txt如下所示：

cmake_minimum_required(VERSION 2.8.11)

set(CMAKE_CXX_COMPILER "/usr/bin/g++")
add_definitions("-march=native")
add_definitions("-std=c++11")
add_definitions("-Werror")
add_definitions("-Wall")
add_definitions("-fdiagnostics-color=always")

project(… CXX)

set(Boost_DEBUG ON)

find_package(OpenCV REQUIRED)
find_package(Boost REQUIRED COMPONENTS filesystem system serialization)
find_package(OpenMP)

if(OPENMP_FOUND)
    set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${OpenMP_C_FLAGS}")
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}")
endif()

set(CMAKE_INCLUDE_CURRENT_DIR ON)

file(GLOB cpp_files *.cpp)

add_subdirectory(…)
add_subdirectory(gui)

在gui子目录中，我有另一个：

cmake_minimum_required(VERSION 2.8.11)

project(…)

set(CMAKE_INCLUDE_CURRENT_DIR ON)
set(CMAKE_AUTOMOC ON)

find_package(Qt4 REQUIRED)
INCLUDE(${QT_USE_FILE})

file(GLOB cpp_files *.cpp)
file(GLOB ui_files *.ui)

QT4_WRAP_UI(UIS_HDRS ${ui_files})

include_directories(${…_SOURCE_DIR})

add_executable(… ${UIS_HDRS} ${cpp_files})
target_link_libraries(… ${OpenCV_LIBS} Qt4::QtGui backend ${Boost_LIBRARIES})
install(TARGETS … DESTINATION bin)

这一切都在Kubuntu 15.04上运行。我不明白为什么当我从命令行调用它时，CMake可以找到Boost，但是当从Qt Creator调用它时无法找到Boost。我怎样才能在Qt Creator中使用它？

答案 0 :(得分：2)

似乎CMake没有在/usr/lib/x86_64-linux-gnu查找库。调试输出显示它正在查看/usr/include/lib;/usr/include/../lib;/usr/include/../lib/;/usr/include/stage/lib;PATHS;C:/boost/lib;C:/boost;/sw/local/lib。

如果您使用的是旧版本的CMake，可以通过升级来修复（我相信最近在FindBoost模块上完成了一些工作）。或者，您应该能够通过适当地设置BOOST_LIBRARYDIR来指示CMake查找正确的文件夹 - 即

cmake . -DBOOST_LIBRARYDIR=/usr/lib/x86_64-linux-gnu
