CMakeListserv.txt的寫法
(1):要求CMake根據指定的源文件生成可執行文件
Demo1:
add_executable(hello main.cpp)
這將從main.cpp源碼文件創建一個叫“hello”（Windows下叫“hello.exe”）的可執行文件。你可以根據自己的需要將C和C++文件混合。在同一個CMakeLists.txt可以有多個可執行文件和庫。同一個源碼文件可以用於不同的目的，源碼可以從其他目標中為每個目的獨立的編譯。
Demo2:
add_executable(demo main.cpp main.h main.rc)
這獎使用main.cpp源文件,main.h文件,main.rc文件構造可執行文件。至於如何使用這些文件,CMake比我們都清楚。
(2):調試CMakeLists.txt的辦法
這個是調試CMakeLists.txt的一個手段啦。不得不學習哦。
演示1如下:
MESSAGE("俺們正在生成項目文件")
會顯示一個警告框。
演示2如下:
MESSAGE(STATUS "俺們正在創建項目文件")
遇到這條指令,會把文字顯示在狀態欄里面(一閃而過，不容易發現)。
演示3如下:
MESSAGE(FATAL_ERROR "嚴重錯誤，俺們搞不定啦")
這條指令會提示出錯，並退出。
(3):使用標准模塊
cmake提供了很多標准模塊，擴展名都是txt.我們可以直接包含進來。就像使用C語言的#include指令一般。比如:
INCLUDE(FindBoost)
一句話,就告訴了CMake“我們的程序需要Boost”。
(4):使用變量 .
SET( MY_SOURCES main.cpp widget.cpp)
MESSAGE(STATUS "my sources: ${MY_SOURCES}")使用SET()命令來為變量設置值。如果你列出了一個以上的字符串，變量將是串列表。列表是一列由分號隔開的字符串。如果只設置個一項，那么這項只有一個值。可以通過${VAR}獲得變量的值。可以使用FOREACH()來迭代一份列表：
FOREACH(next_ITEM ${MY_SOURCES})
MESSAGE(STATUS "next item: ${next_ITEM}")
ENDFOREACH(next_ITEM ${MY_SOURCES})
CMake中的命令是大小寫無關的。變量名和參數名是大小寫相關的。
(5):測試平台相關信息 .
辦法一(這個代碼沒有檢驗過哦)
IF (UNIX)
MESSAGE("這個是UNIX操作系統")
ENDIF (UNIX)
IF (MSVC)
MESSAGE("這個需要做VC的項目文件")
ENDIF (MSVC)
辦法二(這個測試過)
IF (${CMAKE_SYSTEM_NAME} STREQUAL "Windows")
SET(option WIN32)
SET(win32_LIBRARIES comctl32.lib shlwapi.lib shell32.lib odbc32.lib odbccp32.lib kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib)
#SET(defs -DUNICODE -D_UNICODE)
ENDIF (${CMAKE_SYSTEM_NAME} STREQUAL "Windows")
(6):要求CMake根據指定的源文件生成庫文件 .
ADD_LIBRARY: Add a library to the project using the specified source files.
• ADD_LIBRARY(libname [SHARED | STATIC | MODULE] [EXCLUDE_FROM_ALL] source1 source2 ... sourceN)Adds a library target. SHARED, STATIC or MODULE keywords are used to set the library type. If the keyword MODULE appears, the library type is set to MH_BUNDLE on systems which use dyld. On systems without dyld, MODULE is treated like SHARED. If no keywords appear as the second argument, the type defaults to the current value of BUILD_SHARED_LIBS. If this variable is not set, the type defaults to STATIC.
If EXCLUDE_FROM_ALL is given the target will not be built by default. It will be built only if the user explicitly builds the target or another target that requires the target depends on it.
(7):添加查找頭文件的路徑 .
INCLUDE_DIRECTORIES: Add include directories to the build.
INCLUDE_DIRECTORIES([AFTER|BEFORE] [SYSTEM] dir1 dir2 ...)Add the given directories to those searched by the compiler for include files. By default the directories are appended onto the current list of directories. This default behavior can be changed by setting CMAKE_INCLUDE_DIRECTORIES_BEFORE to ON. By using BEFORE or AFTER you can select between appending and prepending, independent from the default. If the SYSTEM option is given the compiler will be told that the directories are meant as system include directories on some platforms.
(8):添加庫文件的搜索路徑 .

LINK_DIRECTORIES: Specify directories in which to search for libraries.
LINK_DIRECTORIES(directory1 directory2 ...)
(9):顯式指定鏈接時需要的庫文件 .

為每個目標分別指定需要鏈接的庫文件(指定部分目標專用的庫文件)
TARGET_LINK_LIBRARIES: Link a target to given libraries.
TARGET_LINK_LIBRARIES(target library1 <debug | optimized> library2 ...)Specify a list of libraries to be linked into the specified target. The debug and optimized strings may be used to indicate that the next library listed is to be used only for that specific type of build
為所有目標統一指定需要的庫文件(指定所有目標都用的庫文件)
LINK_LIBRARIES: Link libraries to all targets added later.
LINK_LIBRARIES(library1 <debug | optimized> library2 ...)This is an old CMake command for linking libraries. Use TARGET_LINK_LIBRARIES unless you have a good reason for every target to link to the same set of libraries.
Specify a list of libraries to be linked into any following targets (typically added with the ADD_EXECUTABLE or ADD_LIBRARY calls). This command is passed down to all subdirectories. The debug and optimized strings may be used to indicate that the next library listed is to be used only for that specific type of build.
(10):顯式實施宏定義 .

用法演示一(文本宏):
ADD_DEFINITIONS(-DDEBUG)
用法演示二(常量宏)
ADD_DEFINITIONS(-DVERSION=1)
ADD_DEFINITIONS: Adds -D define flags to the command line of C and C++ compilers.
ADD_DEFINITIONS(-DFOO -DBAR ...)Adds flags to command line of C and C++ compilers. This command can be used to add any flag to a compile line, but the -D flag is accepted most C/C++ compilers. Other flags may not be as portable.
