c++ - 在 Windows 中无法从 cmake 中找到 MySQL 和 Boost includes/libs

Question

我有以下 CMakeLists.txt:

cmake_minimum_required(VERSION 3.7)
project(TestProject)
message(STATUS "start running cmake...")
find_package(Boost 1.61.0 COMPONENTS system filesystem REQUIRED)
set(SOURCE_FILES main.cpp)
add_executable(TestProject ${SOURCE_FILES})
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
include_directories(TestProject $ENV{MYSQL_INCLUDE_DIR})
target_link_libraries(TestProject $ENV{MYSQL_LIBRARIES})
if (Boost_FOUND)
    message(STATUS "Boost_INCLUDE_DIRS: ${Boost_INCLUDE_DIRS}")
    message(STATUS "Boost_LIBRARIES: ${Boost_LIBRARIES}")
    message(STATUS "Boost_VERSION: ${Boost_VERSION}")
    include_directories(TestProject ${Boost_INCLUDE_DIRS})
    target_link_libraries(TestProject ${Boost_LIBRARIES})
endif ()

当我运行 cmake 时，我得到以下输出:

如果我在 Clion 中使用此 CMakeLists.txt，系统能够找到 Boost 库。以下是我从 CLion

获取的 CMakeCache.txt 中的条目

//The directory containing a CMake configuration file for Boost.
Boost_DIR:PATH=Boost_DIR-NOTFOUND

//Boost filesystem library (debug)
Boost_FILESYSTEM_LIBRARY_DEBUG:FILEPATH=F:/MinGW/lib/libboost_filesystem.a

//Boost filesystem library (release)
Boost_FILESYSTEM_LIBRARY_RELEASE:FILEPATH=F:/MinGW/lib/libboost_filesystem.a

//Path to a file.
Boost_INCLUDE_DIR:PATH=F:/MinGW/include

//Boost library directory DEBUG
Boost_LIBRARY_DIR_DEBUG:PATH=F:/MinGW/lib

//Boost library directory RELEASE
Boost_LIBRARY_DIR_RELEASE:PATH=F:/MinGW/lib

//Boost system library (debug)
Boost_SYSTEM_LIBRARY_DEBUG:FILEPATH=F:/MinGW/lib/libboost_system.a

//Boost system library (release)
Boost_SYSTEM_LIBRARY_RELEASE:FILEPATH=F:/MinGW/lib/libboost_system.a

但是当我从命令行单独运行 cmake 时，我在 CMakeCache.txt 中得到以下内容:

//The directory containing a CMake configuration file for Boost.
Boost_DIR:PATH=Boost_DIR-NOTFOUND

//Boost filesystem library (debug)
Boost_FILESYSTEM_LIBRARY_DEBUG:FILEPATH=Boost_FILESYSTEM_LIBRARY_DEBUG-NOTFOUND

//Boost filesystem library (release)
Boost_FILESYSTEM_LIBRARY_RELEASE:FILEPATH=Boost_FILESYSTEM_LIBRARY_RELEASE-NOTFOUND

//Path to a file.
Boost_INCLUDE_DIR:PATH=Boost_INCLUDE_DIR-NOTFOUND

//Boost system library (debug)
Boost_SYSTEM_LIBRARY_DEBUG:FILEPATH=Boost_SYSTEM_LIBRARY_DEBUG-NOTFOUND

//Boost system library (release)
Boost_SYSTEM_LIBRARY_RELEASE:FILEPATH=Boost_SYSTEM_LIBRARY_RELEASE-NOTFOUND

AIM:在使用 cmake 构建 C++ 项目时，让 MySQL 和 Boost 包含文件和库路径正确

如何设置我的环境。正确以便 cmake 能够找到所有必需的包含文件和库？

Answer 1

也许您的 PATH 变量中没有 F:/MinGW/bin？另外，您使用哪个 MinGW 发行版？我会推荐你​​这个http://www.msys2.org/ .它有非常方便的包管理器。你只要做

pacman -S mingw-w64-x86_64-boost

并且 CMake 在没有任何特殊环境配置的情况下发现了 boost 。
