cmake设置BOOST_LIBRARYDIR

为了设置BOOST_LIBRARYDIR，可以在CMakeLists.txt文件中添加以下代码：

set(BOOST_ROOT "C:/Boost")
set(BOOST_LIBRARYDIR "C:/Boost/lib")
find_package(Boost REQUIRED COMPONENTS system filesystem)
include_directories(${Boost_INCLUDE_DIRS})
target_link_libraries(your_target_name ${Boost_LIBRARIES})

其中，BOOST_ROOT是Boost库的根目录，BOOST_LIBRARYDIR是Boost库的lib目录。这里使用了find_package命令来查找Boost库，并将其包含路径添加到include_directories中，将库文件添加到target_link_libraries中。

这段代码是一个 CMakeLists.txt 文件，用于构建一个名为 "mcu_kit" 的项目。下面是对每行代码的详细注释：

cmake_minimum_required(VERSION 3.8.0 FATAL_ERROR)

指定最低的 CMake 版本，如果当前版本不符合要求，则提示错误。

project(mcu_kit VERSION 0.1.0 DESCRIPTION "mcu-kit SDK" LANGUAGES C)

定义项目名称、版本、描述和使用的编程语言。

set(PROJECT_BRIEF "vDiscovery")

设置一个变量，用于描述项目简介。

set(CMAKE_C_STANDARD 11)
set(CMAKE_C_EXTENSIONS ON)
set(CMAKE_C_STANDARD_REQUIRED ON)
set(CMAKE_CXX_STANDARD 11)

指定使用的 C 和 C++ 标准版本。

set(CMAKE_POSITION_INDEPENDENT_CODE ON)

启用位置独立代码（PIC）选项。

add_compile_options(-Wall)

添加编译选项，这里添加了 -Wall 选项，表示开启所有警告。

list(APPEND CMAKE_MODULE_PATH "${PROJECT_SOURCE_DIR}/cmake")

将自定义的 CMake 模块路径添加到 CMAKE_MODULE_PATH 变量中。

include(CMakePrintHelpers)
include(ConfigureChecks)

包含两个自定义的 CMake 模块，用于输出调试信息和配置检查。

if(EXISTS "${PROJECT_SOURCE_DIR}/config.cmake")
    include(config.cmake)
else()
    message(FATAL_ERROR "Can't find cmake.config file")
endif()

如果存在 config.cmake 文件，则包含它，否则输出错误信息并停止构建。

if(${CMAKE_CROSSCOMPILING})
    set(LV_SIMULATOR_ON_PC OFF)
else()
    set(LV_SIMULATOR_ON_PC ON)
endif()

根据交叉编译标志设置变量 LV_SIMULATOR_ON_PC。如果正在交叉编译，则设置为 OFF；否则设置为 ON。

configure_file(
    "${PROJECT_SOURCE_DIR}/base/base_sdk_version.h.in"
    "${PROJECT_SOURCE_DIR}/base/base_sdk_version.h"
)
configure_file(
    "${PROJECT_SOURCE_DIR}/base/base_config.h.in"
    "${PROJECT_SOURCE_DIR}/base/base_config.h"
)

配置文件模板，用于生成编译时需要的头文件。

set(CMAKE_INSTALL_BINDIR ${CMAKE_INSTALL_PREFIX}/bin)
set(CMAKE_INSTALL_SBINDIR ${CMAKE_INSTALL_PREFIX}/sbin)
set(CMAKE_INSTALL_LIBDIR ${CMAKE_INSTALL_PREFIX}/lib)
set(CMAKE_INSTALL_INCLUDEDIR ${CMAKE_INSTALL_PREFIX}/include)
set(CMAKE_INSTALL_SYSCONFDIR ${CMAKE_INSTALL_PREFIX}/etc)
set(CMAKE_INSTALL_SHARESTATEDIR ${CMAKE_INSTALL_PREFIX}/com)
set(CMAKE_INSTALL_LOCALSTATEDIR ${CMAKE_INSTALL_PREFIX}/var)
set(CMAKE_INSTALL_INFODIR ${CMAKE_INSTALL_PREFIX}/info)
set(CMAKE_INSTALL_LOCALEDIR ${CMAKE_INSTALL_PREFIX}/locate)
set(CMAKE_INSTALL_MANDIR ${CMAKE_INSTALL_PREFIX}/man)
set(CMAKE_INSTALL_DOCDIR ${CMAKE_INSTALL_PREFIX}/doc)
set(CMAKE_INSTALL_RESDIR ${CMAKE_INSTALL_PREFIX})

设置安装目录的各个子目录。

include(PrepareInstall)

包含一个自定义的 CMake 模块，用于准备安装目录。

set(KIT_ROOT_DIR ${CMAKE_SOURCE_DIR})

设置变量 KIT_ROOT_DIR 的值为源代码目录。

add_subdirectory("base")
add_subdirectory("lib")
add_subdirectory("drivers")
add_subdirectory("framework")
add_subdirectory("sysapp")
add_subdirectory("app")

添加子目录，用于构建项目的各个模块。每个子目录都包含了相应的 CMakeLists.txt 文件。

怎么设置 CMAKE_CXX_COMPILER

要设置 CMAKE_CXX_COMPILER，可以使用以下两种方法之一：

1. 在命令行中传递参数

可以在运行 cmake 命令时，在命令行中传递 CMAKE_CXX_COMPILER 参数来指定编译器。例如，如果你想使用 g++ 编译器，可以这样做：

cmake -DCMAKE_CXX_COMPILER=g++ <path_to_source>

2. 在 CMakeLists.txt 文件中设置

也可以在项目的 CMakeLists.txt 文件中设置 CMAKE_CXX_COMPILER 变量。例如：

set(CMAKE_CXX_COMPILER g++)

这样设置后，每次运行 cmake 命令时，都会使用指定的编译器。
