6. myenv in build is first7. Built target EchoEnv 2.1.2 缓存变量 缓存变量可以通过$CACHE{<name>} 语法来引用,而设置一个缓存变量使用set(<variable> <value> CACHE <type> <docstring> [FORCE])指令,与用于普通变量的set() 指令相比,缓存变量的设定中有一些必需参数和关键字(CACHE &FORCE)。与环境...
首先说明如何修改或创建一个环境变量,使用set(ENV{<variable>} <value>)指令用以声明,使用unset(ENV{<variable>})来清除某一个环境变量,其中ENV表示环境变量标志性前缀,variable指变量名称,value则为变量值,需要注意的是设定或读取环境变量时,都通过ENV前缀来访问环境变量,读取环境变量值时,要在ENV前加$符号;但if...

set(... CACHE[FORCE]) 将缓存变量variable设置为值...,默认情况下缓存变量的值不会被覆盖,使用FORCE选项则会覆盖现有变量。缓存变量可以通过CMAKE的GUI界面的add entry按钮来增加。缓存变量的实质为可以跨层级进行传递的变量,类似于全局变量。使用CACHE的同时,要设定和,可以理解为所存入变量类型,为变量的描述。缓存...

if(<variable|string>STREQUAL<variable|string>) 我们在书写某个路径的时候,可能由于误操作会多写几个分隔符,比如把/a/b/c写成/a//b///c,此时通过STREQUAL对这两个字符串进行比较肯定是不相等的,但是通过PATH_EQUAL去比较两个路径,得到的结果确实相等的,可以看下面的例子: ...

aux_source_directory(<dir> <variable>) 因此,可以修改 CMakeLists.txt 如下: # CMake 最低版本号要求 cmake_minimum_required (VERSION 2.8) # 项目信息 project (Demo2) # 查找当前目录下的所有源文件 # 并将名称保存到 DIR_SRCS 变量 aux_source_directory(. DIR_SRCS) # 指定生成目标 add_executabl...
A good way to check ifhipccis available is to just usewhich. which hipcc I don't havehipccset, so it just tells me its not found, hence why I referenced the absolute paths. Passing the variables before the command just passes the key/value pairs to the CLI app as it executes. ...
If you choose this option, CLion will not force any generator explicitly, and CMake will decide which generator to use. By default, this is controlled by the CMAKE_GENERATOR environment variable. Alternatively, you can set the generator in CMake options via -G. When the Generator field is ...
