CMake中的两种变量(Variable types in CMake) 在CMake中存在两种变量:normal variables and cache varialbes .正常变量就像是脚本内部变量,相当于程序设计中定义的局部变量那样。而CMakeLists.txt相当于一个函数,第一个执行的CMakeLists.txt相当于主函数。所以正常变量。不能跨越CMakeLists.txt文件(they are not p...
include(CheckVariableExists) check_function_exists(ftime HAVE_FTIME) check_type_size 检测一个类型的长度。也可以用此函数替代 check_source_runs 等来查询当前架构。其原型为: check_type_size(<type> <variable> [BUILTIN_TYPES_ONLY] [LANGUAGE <language>]) # needs "include(CheckTypeSize)" 示例为: ...
当然,假如参数里的值本身就有空格或者分号,那我们需要给其加上引号,例如: set(TEST_VARIABLE "A TEST") #或 set(TEST_VARIABLE "A;TEST") 如果我们要使用变量,可以使用${},例如: ${TEST_VARIABLE} 为了方便调试,我们先引入一个message()命令,它可以打印信息,比如,我们将上面的变量打印一下,如下: message(...
可以为find_*或 find 模块启用 DEBUG 消息。 define_property()新增了INITIALIZE_FROM_VARIABLE选项。 CMAKE_<SYSTEM_>IGNORE_PREFIX_PATH可以控制find_*的查找路径。 新增<CMAKE_>LINK_LIBRARIES_ONLY_TARGETS强制只链接目标(非常适合查找错误!) IMPORTED_NO_SYSTEM可强制从目标中删除 SYSTEM 的新属性。 FindGTest在...
if(NOT CMAKE_BUILD_TYPE AND NOT CMAKE_CONFIGURATION_TYPES) message("Setting build type to 'RelWithDebInfo' as none was specified.") set(CMAKE_BUILD_TYPE RelWithDebInfo CACHE STRING "Choose the type of build." FORCE) # Set the possible values of build type for cmake-gui ...
CMAKE_CFG_INTDIR Deprecated since version 3.21: This variable has poor support on Ninja Multi-Config, and predates the existence of the $<CONFIG> generator expression. Use $<CONFIG> instead. Build-time reference to per-configuration output subdirectory. For native build systems supporting multiple ...
But can be extended to provide other build types. See also CMAKE_BUILD_TYPE. cmake 2.8.6 Last change: June 17, 2014 12 User Commands cmakevars(1) CMAKE_DISABLE_FIND_PACKAGE_<PackageName> Variable for disabling find_package() calls. Every non-REQUIRED find_package() call in a project...
从命令行设置list类型的CMake变量,可以使用CMake的"-D"选项来设置变量的值。对于list类型的变量,可以使用分号来分隔不同的元素。 以下是设置list类型的CMake变量的示例命令行指令: 代码语言:txt 复制 cmake -DVAR_NAME="value1;value2;value3" .. 其中,VAR_NAME是要设置的变量名,"value1;value2;value3...
This is the default for most product types. No Common Blocks (GCC_NO_COMMON_BLOCKS) In C, allocate even uninitialized global variables in the data section of the object file, rather than generating them as common blocks. This has the effect that if the same variable is declared (without ...
The default value of this command is the four build types given above, but you can extend it to have other build types. For example: # adding two custom build types to the cached value # variable CMAKE_CONFIGURATION_TYPES should be defined before other definitions: set(CMAKE_CONFIGURATION_...
