cmake使用总结

官方文档https://cmake.org/cmake/help/v3.7/

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( [WIN32] [MACOSX_BUNDLE]
               [EXCLUDE_FROM_ALL]
               source1 [source2 ...])

# 添加库。 从源文件source1, source2...生成库name(静态库，动态库)

add_library( [STATIC | SHARED | MODULE]
            [EXCLUDE_FROM_ALL]
            source1 [source2 ...])

# 显示信息

message([] "message to display" ...)

# 添加build子文件夹。告诉CMake执行source_dir下的 CMakeLists.txt文件，编译source_dir中的源代码

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

aux_source_directory( )

# 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 ...)

# 设置链接库。该命令之后的所有target都要链接该命令中设置的库

Link libraries to all targets added later.

link_libraries([item1 [item2 [...]]] [[debug|optimized|general] ] ...)

# 设置预编译宏。e.g. Debug模式下add_definitions(-g -D_DEBUG); Release模式下add_definitions(-DNDEBUG -O2)

add_definitions(-DFOO -DBAR ...)

# 用户可选择的选项。option(debug "is debug mode?" OFF).可以通过-D选择不同的选项。如cmake ../source -Ddebug=ON;cmake ../source -Ddebug=OFF

option( "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

set (CMAKE_DEBUG_POSTFIX "d")  #设置debug模式时，输出产物名加后缀d

unset (CMAKE_DEBUG_POSTFIX) # 取消CMAKE_DEBUG_POSTFIX变量的设置

# 逻辑判断

if()

if(NOT )

if( AND )

if( OR )

if(DEFINED )

if((expression) AND (expression OR (expression)))

if( MATCHES regex) if( LESS ) if( GREATER ) if( EQUAL ) if( STRLESS ) if( STRGREATER ) if( STREQUAL )

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

FIND_PACKAGE( OpenMP REQUIRED)
if(OPENMP_FOUND)
message("OPENMP FOUND")
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${OpenMP_C_FLAGS}")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}")
set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} ${OpenMP_EXE_LINKER_FLAGS}")
set(CMAKE_SHARE_LINKER_FLAGS "${CMAKE_SHARE_LINKER_FLAGS} ${OpenMP_SHARE_LINKER_FLAGS}")
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
