为了处理更高级的场景,我们将介绍用于安装文件和目录的低级命令,以及用于执行自定义脚本和 CMake 命令的命令。 接下来,我们将学习如何设置可重用的 CMake 包,以便它们可以被其他项目通过调用find_package()发现。具体来说,我们将解释如何确保目标和它们的定义不会固定在文件系统的特定位置。我们还将讨论如何编写基本和...
FIND_PROGRAM(<VAR> name1 path1 path2 ...) VAR变量代表包含这个程序的全路径。 FIND_PACKAGE(<name> [major.minor] [QUIET][NO_MODULE] [[REQUIRED|COMPONENTS] [componets...]]) 用来调用预定义在CMAKE_MODULE_PATH下的Find<name>.cmake模块,你也可以自己 定义Find<name>模块,通过SET(CMAKE_MODULE_P...

C requires that if the exponent is representable using only one or two digits, then only two digits are to be printed. In Visual Studio 2005 a global conformance switch was added: _set_output_format. A program could call this function with the argument _TWO_DIGIT_EXPONENT, to enable ...
The compiler translates your source program into machine language object code that the TMS320C28x can execute. Source code must be compiled, assembled, and linked to create an executable object file. All of these steps are executed at once by using the compiler.2.1...
You can find this pattern everywhere. Any non-voidfunction returns data in this way. Every C program has amainfunction that already provides a return value to its caller (such as the operating system). Applied to Running Example ApplyingReturn Value was simple. Now you have a new diagnostic ...
An algorithm is said to be efficient if it solves the problem within its resource constraints. Space Time The choice of data structure and algorithm can make the difference between a program running in a few seconds or many days. What is data structure Why you come here * * * 研究数据...
