How to set the global variable in a function for cmake? PARENT_SCOPE is only for parent, it won't work if you have other non-parent script that want to see it as well. You need cache for the true "global-like" variable. In your case, use: SET(source_list "${source_list}" CACHE INTERNAL "source_list")

I create a function to add some file path strings to a global list variable. My CMakeLists.txt: set (source_list "nothing") function (test file_path) list (APPEND source_list $ {file_path}) endfunction (test) test (abc.txt) test (def.txt) message ("At last, the source_list is:\"$ {source_list}\"") The cmake output: At last, the source_list is:"nothing".

Note. When specifying index values, if <element index> is 0 or greater, it is indexed from the beginning of the list, with 0 representing the first list element. If <element index> is -1 or lesser, it is indexed from the end of the list, with -1 representing the last list element. Be careful when counting with negative indices: they do not start from 0. -0 is equivalent to 0, the first list elem

It's important to know how CMake distinguishes between lists and plain strings. When you write: set (VAR "a b c") you create a string with the value "a b c". But when you write this line without quotes: set (VAR a b c) You create a list of three items instead: "a", "b" and "c". Non-list variables are actually lists too (of a single element).

But CMake does also know global "cached variables" (persisted in CMakeCache.txt ). And if normal and cached variables of the same name exist in the current ...

CMAKE_VS_GLOBALS ¶ New in version 3.13. List of Key=Value records to be set per target as target properties VS_GLOBAL_<variable> with variable=Key and value Value. For example: set (CMAKE_VS_GLOBALS "DefaultLanguage=en-US" "MinimumVisualStudioVersion=14.0" )

Example. Mostly you will use "normal variables":. set(VAR TRUE) set(VAR "main.cpp") set(VAR1 ${VAR2}) But CMake does also know global "cached variables" (persisted in CMakeCache.txt).And if normal and cached variables of the same name exist in the current scope, normal variables do hide the cached ones:

This page documents variables that are provided by CMake or have meaning to CMake when set by project code. For general information on variables, see the ...

I'm writing a CMakeLists.txt to generate files and compile the generated files. I create a function to add some file path strings to a global list variable.

30.09.2019 · LIST与SET命令类似，即使列表本身是在父域中定义的，LIST命令也只会在当前域创建新的变量，要想将这些操作的结果向上传递，需要通过SET PARENT_SCOPE， SET CACHE INTERNAL或运用其他值域扩展的方法。. 注意：cmake中的list是以分号隔开的一组字符串。. 可以使用set命令 ...

I looks like that it is the directory where it is in and all > subdirectories? ... Is there a way to make the scope of variables global?

get_property(source_list GLOBAL PROPERTY source_list_property) I used in examples above the different names for property (source_list_property) and for variable (source_list). Maybe it is better to use the same name. But point is to use a property as global variables, and not about naming. Such global properties aren't in cache.

22.04.2020 · Inside a cmake module, define a property to contain the list of targets. After using add_executable () or add_library (), use that macro to insert the target in the list. My use case was to generate an installation option for each target automatically. The list of targets can be used for something else I guess.

You create a list of three items instead: "a", "b" and "c". Non-list variables are actually lists too (of a single element). Lists can be operated on with the list () command, which allows concatenating lists, searching them, accessing arbitrary elements and so on ( documentation of list () ). Somewhat confusing, a list is also a string. The line

If the variable is intended for CMake use only, prefer to use CMake-style directory separators (forward slash) in it.

A list in cmake is a ; separated group of strings. To create a list the set command can be used. For example, set(var a b c d e) creates a list with a;b;c;d ...

set¶. Set a normal, cache, or environment variable to a given value. See the cmake-language(7) variables documentation for the scopes and interaction of normal variables and cache entries..
