CMake是一个跨平台的安装(编译)工具,可以用简单的语句来描述所有平台的安装(编译过程),输出各种各样的makefile或者project文件。CMake”这个名字是“cross platform make”的缩写。

1. $> cmake ../sdk -Ddebug=ON
2. $> make
3. $> make install

第一条命令用于根据路径../sdk下的CMakeLists.txt生成Makefile文件；第二条命令执行Makefile文件，编译程序，生成可执行文件；第三条命令安装生成的可执行文件。 


“#”后面为注释的内容。 

 

  CMakeLists.txt中的命令可以全部大写，或者全部小写。 

 

  # 指定工程名 e.g. 指定本工程的工程名为test_math 

 
project(test_math)
# 定义变量 e.g. 定义SLNDIR变量，变量值为../../。变量的使用方法为${variable name}
set(SLNDIR ../../)
# 从文件加载CMake命令 e.g. 加载../../prj.mak/sp.cmake文件的所有命令
include(${SLNDIR}prj.mak/sp.cmake)
# 添加包含路径，编译器能这些路径中寻找头文件 e.g. 添加两个路径
include_directories (${SLNDIR}src/include ${SLNDIR}src/3rd/include )
# 添加可执行文件。从源文件source1, source2...生成可执行文件name
add_executable(<name> [WIN32] [MACOSX_BUNDLE]

            [EXCLUDE_FROM_ALL]

add_subdirectory(source_dir [binary_dir]
                 [EXCLUDE_FROM_ALL])#  收集所有的源文件。将dir路径下的所有源文件都存储在variable中

# 设置链接库的搜索路径。相当于gcc中的-L（大写L）
Specify directories in which the linker will look for libraries.
 
link_directories(directory1 directory2 ...)

option(<option_variable> "help string describing option" [initial value])option_variable可以通过${option_variable}进行访问，其值为ON或者OFF
# 设置变量，取消变量

cmake操作系统平台的判断
1. MESSAGE(STATUS "operation system is ${CMAKE_SYSTEM}") 
 
1. IF (CMAKE_SYSTEM_NAME MATCHES "Linux")  
2.     MESSAGE(STATUS "current platform: Linux ")  
3. ELSEIF (CMAKE_SYSTEM_NAME MATCHES "Windows")  
4.     MESSAGE(STATUS "current platform: Windows")  
5. ELSEIF (CMAKE_SYSTEM_NAME MATCHES "FreeBSD")  
6.     MESSAGE(STATUS "current platform: FreeBSD")  
7. ELSE ()  
8.     MESSAGE(STATUS "other platform: ${CMAKE_SYSTEM_NAME}")  
9. ENDIF (CMAKE_SYSTEM_NAME MATCHES "Linux")  
 
1. IF (WIN32)  
2.     MESSAGE(STATUS "Now is windows")  
3. ELSEIF (APPLE)  
4.     MESSAGE(STATUS "Now is Apple systens.")  
5. ELSEIF (UNIX)  
6.     MESSAGE(STATUS "Now is UNIX-like OS's. Including aPPLE os x  and CygWin")  
7. ENDIF () 
 

  CMake注意事项： 

 

  1.使用set设置CMAKE_CXX_FLAGS等变量时不要覆盖，尽量保留系统默认的一些值，在这些值后面添加就行了。例如： 

 

  set(LOCAL_CXX_FLAGS "-fPIC -fPE") 

 

  set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${LOCAL_CXX_FLAGS}") 

 
 

  CMake调用openmp 

 
1. FIND_PACKAGE( OpenMP REQUIRED)  
2. if(OPENMP_FOUND)  
3. message("OPENMP FOUND")  
4. set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${OpenMP_C_FLAGS}")  
5. set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}")  
6. set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} ${OpenMP_EXE_LINKER_FLAGS}") 
7. set(CMAKE_SHARE_LINKER_FLAGS "${CMAKE_SHARE_LINKER_FLAGS} ${OpenMP_SHARE_LINKER_FLAGS}")
8. endif()  
 

  交叉编译 

 
6.1     基本概念
宿主机host是执行编译、链接嵌入式软件的计算机；目标机target是运行嵌入式软件的硬件平台。通常我们用的PC机(window系统或者liunx系统)就是宿主机，而客户使用的车机（QNX系统）、手机（Andorid系统）则是目标机。
在宿主机host上要生成目标机target的程序就是交叉编译。交叉编译时需要修改以下内容：
Ø  修改编译器；
Ø  修改依赖库；
Ø  修改头文件；
使用CMake进行交叉编译就是要告诉CMake目标机target是什么平台、使用什么编译器、到哪里寻找依赖库、到哪里寻到头文件。CMake使用一些内建变量定义上述内容。
Ø  CMAKE_SYSTEM_NAME: 即你目标机target所在的操作系统名称，比如ARM或者Linux你就需要写"Linux",如果Windows平台你就写"Windows",如果你的嵌入式平台没有相关OS你即需要写成"Generic",只有当CMAKE_SYSTEM_NAME这个变量被设置了，CMake才认为此时正在交叉编译，它会额外设置一个变量CMAKE_CROSSCOMPILING为TRUE.
Ø  CMAKE_C_COMPILER: 顾名思义，即C语言编译器，这里可以将变量设置成完整路径或者文件名，设置成完整路径有一个好处就是CMake会去这个路径下去寻找编译相关的其他工具比如linker,binutils等，如果你写的文件名带有arm-elf等等前缀，CMake会识别到并且去寻找相关的交叉编译器。
Ø  CMAKE_CXX_COMPILER: 同上，此时代表的是C++编译器
Ø  CMAKE_FIND_ROOT_PATH: 代表了一系列的相关文件夹路径的根路径的变更
Ø  CMAKE_FIND_ROOT_PATH_MODE_PROGRAM: 对FIND_PROGRAM()起作用，有三种取值，NEVER,ONLY,BOTH,第一个表示不在你CMAKE_FIND_ROOT_PATH下进行查找，第二个表示只在这个路径下查找，第三个表示先查找这个路径，再查找全局路径，对于这个变量来说，一般都是调用宿主机的程序，所以一般都设置成NEVER
Ø  CMAKE_FIND_ROOT_PATH_MODE_LIBRARY: 对FIND_LIBRARY()起作用，表示在链接的时候的库的相关选项，因此这里需要设置成ONLY来保证我们的库是在交叉环境中找的.
Ø  CMAKE_FIND_ROOT_PATH_MODE_INCLUDE: 对FIND_PATH()和FIND_FILE()起作用，一般来说也是ONLY
与交叉编译相关的这些变量如何传递给CMake了？最为方便的一个方法就是将相关的变量设置都放进一个文件(cmake脚本)中去，然后将该文件通过CMAKE_TOOLCHIAIN_FILE传递给CMake, 例如：
cmake-DCMAKE_TOOLCHIAIN_FILE="/path/to/toolchain-file" ..
6.2    附上一个CMake官方文档中的toolchian-file的小例子，这样我们就会对如何写toolchain-file文件有了感性认识：
# this one is important
SET(CMAKE_SYSTEM_NAMELinux)
#this one not so much
SET(CMAKE_SYSTEM_VERSION 1)
# specify the crosscompiler
SET(CMAKE_C_COMPILER   /opt/eldk-2007-01-19/usr/bin/ppc_74xx-gcc)
SET(CMAKE_CXX_COMPILER/opt/eldk-2007-01-19/usr/bin/ppc_74xx-g++)
# where is the targetenvironment
SET(CMAKE_FIND_ROOT_PATH  /opt/eldk-2007-01-19/ppc_74xx/home/alex/eldk-ppc74xx-inst)
# search for programs inthe build host directories
SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAMNEVER)
# for libraries and headersin the target directories
SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARYONLY)
SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
6.3    编译生成Android平台上的程序，需要用到GOOGLE为我们提供了的Android NDK用来做Native(C/C++)的build。Android NDK中包含了整套的编译器、系统库、头文件、调试器等。
使用CMake交叉编译Android平台上的程序，就需要：
Ø  指明目标平台为Android
Ø  指明目标硬件是ARM还是X86
Ø  指明ndk level version
Ø  用ndk提供的编译器
Ø  从ndk安装目录搜寻依赖库和头文件
我们可以自己动手编写toolchain-file，设置相应的变量。这也比较麻烦。
幸运的是，我们有Android-cmake项目可以帮忙。该项目生成了一个名为android.toolchain.cmake的toolchain-file文件，该文件帮我们设置了大部分的变量。我们需要做的就是指定cmake的toolchain file为这个项目里面的android.toolchain.cmake文件，然后设置好Android NDK路径即可。
# Usage Linux:
export ANDROID_NDK=/absolute/path/to/the/android-ndk
mkdir build && cdbuild
cmake-DCMAKE_TOOLCHAIN_FILE=path/to/the/android.toolchain.cmake ..
make -j8
make install
# Usage Windows:
SETANDROID_NDK=C:\absolute\path\to\the\android-ndk
mkdir build && cdbuild
cmake.exe -G"MinGWMakefiles" ^
 -DCMAKE_TOOLCHAIN_FILE=path\to\the\android.toolchain.cmake ^
 -DCMAKE_MAKE_PROGRAM="%ANDROID_NDK%\prebuilt\windows\bin\make.exe"^
  ..
cmake.exe --build . --target install--clean-first

安装cmake command line tool 的方法：

sudo "/Applications//Contents/bin/cmake-gui" --install

使用CMake的file()函数可以操作文件， 如读取文件内容、写文件

在写文件的时候，会将形如${var}字符串替换成CMAKE中的变量

如果确实需要写入${var}字符串，则需要进行转义。转义方法：在$符号前加转义符，例如：

\${var}
