一 为什么使用CMake
CMake是一个比make更高级的编译配置工具，它可以根据不同平台、不同的编译器，生成相应的Makefile或者vcproj项目。通过编写CMakeLists.txt，可以控制生成的Makefile，从而控制编译过程。CMake自动生成的Makefile不仅可以通过make命令构建项目生成目标文件，还支持安装（make install）、测试安装的程序是否能正确执行（make test，或者ctest）、生成当前平台的安装包（make package）、生成源码包（make package_source）、产生Dashboard显示数据并上传等高级功能，只要在CMakeLists.txt中简单配置，就可以完成很多复杂的功能，包括写测试用例。如果有嵌套目录，子目录下可以有自己的CMakeLists.txt。总之很强大！
三 CMake基本使用和语法
command （args ...）
command 是命令名，大小写无关（注意：变量是大小写相关的）
args 是参数，参数如果有空格，应该用双引号括起来
变量引用用${VAR}语法
set命令可以将多变量可以放在一起，合成为一个变量,如下所示
set（Foo a b c）
command(${Foo})=command(a b c)
command("${Foo}")=command("a b c")
CMake可以直接获取系统环境变量和Windows注册值。为了获取系统环境变量，需要语法
$ENV{VAR}
四 CMake中的Hello World
CMakeLists.txt文件中
project(Hello) add_executable(Hello Hello.c)
这只是最简单的版本，下面还有一个复杂一些的版本
cmake_minimum_required (2.6)
project (HELLO)
set (HELLO_SRCS Hello.c File2.c File3.c)
if (win32)
set (HELLO_SRCS ${HELLO_SRCS} WinSupport.c)
else ()
set (HELLO_SRCS ${HELLO_SRCS} UnixSupport.c)
endif ()
add_executable (Hello ${HELLO_SRCS})
#look for Tcl library
find_library (TCL_LIBRARY NAMES tcl tcl84 tcl83 tcl82 tcl80 PATHS /usr/lib /usr/local/lib)
if (TCL_LIBRARY)
target_link_library (HELLO ${TCL_LIBRARY})
endif ()
五 Run Cmake
cd Hello
cmake ..
make
六 CMake帮助文档
安装完之后，进入/usr/share/cmake
目录形式如下
.
├── completions
├── editors
│ ├── emacs
│ └── vim
├── Help

其中需要注意的是Help目录和Modules目录，Help目录为帮助文档，Modulues目录为find_package指令的查找目录之一。
cmake --help
我们可以查看cmake帮助，这个很全，比如显示cmake的指令
cmake --help-command-list
add_compile_options add_custom_command add_custom_target add_definitions add_dependencies add_executable add_library add_subdirectory add_test aux_source_directory break build_command build_name cmake_host_system_information cmake_minimum_required cmake_policy configure_file continue create_test_sourcelist ctest_build ctest_configure ctest_coverage ctest_empty_binary_directory ctest_memcheck ctest_read_custom_files ctest_run_script ctest_sleep ctest_start ctest_submit ctest_test ctest_update ctest_upload define_property else elseif enable_language enable_testing endforeach endfunction endif endmacro endwhile exec_program execute_process export export_library_dependencies file find_file find_library find_package find_path find_program fltk_wrap_ui foreach function get_cmake_property get_directory_property get_filename_component get_property get_source_file_property get_target_property get_test_property if include include_directories include_external_msproject include_regular_expression install install_files install_programs install_targets link_directories link_libraries list load_cache load_command macro make_directory mark_as_advanced math message option output_required_files project qt_wrap_cpp qt_wrap_ui remove remove_definitions return separate_arguments set set_directory_properties set_property set_source_files_properties set_target_properties set_tests_properties site_name source_group string subdir_depends subdirs target_compile_definitions target_compile_features target_compile_options target_include_directories target_link_libraries target_sources try_compile try_run unset use_mangled_mesa utility_source variable_requires variable_watch while write_file
再如cmake定义的变量
cmake --help-variable-list
