CMake 使用入门

CMake is a cross-platform Makefile generator
1 CMakeLists.txt ——helloworld
cmake_minimum_required(VERSION 2.8.9) project (hello) add_executable(hello helloworld.cpp)
The first line is CMake Version for this project, which is major version 2, minor version 8, and patch version 9 in this example.
The second line is the project() command that sets the project name
The third line is the add_executable() command, which requests that an executable is to be built using the helloworld.cpp source file. The first argument to the
add_executable() function is the name of the executable to be built, and the second argument is the source file from which to build the executable.
编译方法：
1 cd $YOUR_DIR/exploringBB/extras/cmake/helloworld 2 cmake . 3 make
2 使用单独的build目录放置编译结果
1 mkdir build 2 cd build 3 cmake .. 4 make
3 多目录结构的CMakeLists.txt
1 cmake_minimum_required(VERSION 2.8.9) 2 project(directory_test) 3 4 #Bring the headers, such as Student.h into the project 5 include_directories(include) 6 7 #Can manually add the sources using the set command as follows: 8 #set(SOURCES src/mainapp.cpp src/Student.cpp) 9 10 #However, the file(GLOB...) allows for wildcard additions: 11 file(GLOB SOURCES "src/*.cpp") 12 13 add_executable(testStudent ${SOURCES})
4 静态库结构的示例
1 cmake_minimum_required(VERSION 2.8.9) 2 project(directory_test) 3 set(CMAKE_BUILD_TYPE Release) 4 5 #Bring the headers, such as Student.h into the project 6 include_directories(include) 7 8 #However, the file(GLOB...) allows for wildcard additions: 9 file(GLOB SOURCES "src/*.cpp") 10 11 #Generate the shared library from the sources 12 add_library(testStudent SHARED ${SOURCES}) 13 14 #Set the location for library installation -- i.e., /usr/lib in this case 15 # not really necessary in this example. Use "sudo make install" to apply 16 install(TARGETS testStudent DESTINATION /usr/lib)
结果如下：
1 -rw-rw-r--. 1 hadoop hadoop 12355 Jul 28 02:36 CMakeCache.txt 2 drwxrwxr-x. 5 hadoop hadoop 4096 Jul 28 02:36 CMakeFiles 3 -rw-rw-r--. 1 hadoop hadoop 2594 Jul 28 02:36 cmake_install.cmake 4 -rw-rw-r--. 1 hadoop hadoop 3192 Jul 28 02:36 libtestStudent.a 5 -rw-rw-r--. 1 hadoop hadoop 6820 Jul 28 02:36 Makefile
安装库：
1 sudo make install
5 引用外部链接库的方法
1 cmake_minimum_required(VERSION 2.8.9) 2 project (TestLibrary) 3 4 #For the shared library: 5 set ( PROJECT_LINK_LIBS libtestStudent.so ) 6 link_directories( ~/exploringBB/extras/cmake/studentlib_shared/build ) 7 8 #For the static library: 9 #set ( PROJECT_LINK_LIBS libtestStudent.a ) 10 #link_directories( ~/exploringBB/extras/cmake/studentlib_static/build ) 11 12 include_directories(~/exploringBB/extras/cmake/studentlib_shared/include) 13 14 add_executable(libtest libtest.cpp) 15 target_link_libraries(libtest ${PROJECT_LINK_LIBS} )
