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).

01.08.2013 · Three typical CMake string concatenation methods. While the answer to this particular question will be best handled via set or string, there is a third possibility which is list if you want to join strings with an arbitrary character.. set() Just combine strings like in bash

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;e, and set (var "a b c d e") creates a string or a list with one item in it. (Note macro arguments are not variables, and therefore cannot be used in LIST commands.)

And since everything in CMake is a string, this means that a list is a semicolon-separated sequence of strings, making itself a string.

This answer is not useful. Show activity on this post. You can use the separate_arguments command. cmake_minimum_required (VERSION 2.6) set (SEXY_STRING "I love CMake") message (STATUS "string = $ {SEXY_STRING}") # string = I love CMake set ( SEXY_LIST $ {SEXY_STRING} ) separate_arguments (SEXY_LIST) message (STATUS "list = $ {SEXY_LIST ...

If you want to convert a string to a list you. can do it like this: set (list $ {string}) That will make the space separated list string into a ; separated list. If you want to keep string a string you need quotes: set (newstring "$ {string}"). Converting a list back into a …

To join multiple strings, which are not part of a list, use JOIN operator from string() command. list(SUBLIST <list> <begin> <length> <output variable>).

Get an element from <json-string> at the location given by the list of <member|index> arguments. Array and object elements will be returned as a JSON string. Boolean elements will be returned as ON or OFF. Null elements will be returned as an empty string. Number and string types will be returned as strings.

You can use the separate_arguments command. cmake_minimum_required(VERSION 2.6) set(SEXY_STRING "I love CMake") message(STATUS "string = ${SEXY_STRING}") # ...

There is no such thing as a list with spaces in CMake, that is a string. So, no there is no way to use the list command on strings directly.

13.01.2017 · CMake's lists are semicolon-delimited. So "Hello" "There" "World" is internally represented as Hello;There;World.So a simple solution is to replace semicolons with newlines: string (REPLACE ";" "\n" txt "${txt}") This works in this example, however lets try a more complicated example:

Replace your separator by a ; . I don't see any other way to do it. cmake_minimum_required(VERSION 2.8) set(SEXY_STRING "I love CMake") ...

cmake_minimum_required (VERSION 2.8) set(MY_PROGRAM_VERSION "2.5.1") string (REPLACE "." ";" VERSION_LIST $ {MY_PROGRAM_VERSION}) list (GET VERSION_LIST 0 MY_PROGRAM_VERSION_MAJOR) list (GET VERSION_LIST 1 MY_PROGRAM_VERSION_MINOR) list (GET VERSION_LIST 2 MY_PROGRAM_VERSION_PATCH) , You can use the following helper function to automatically have the version component variables set up:

15.03.2021 · A CMake list is a semicolon-separated sequence of elements. And since everything in CMake is a string, this means that a list is a semicolon-separated sequence of strings, making itself a string. Because who needs a type system, right? This may also be true the other way around – a string may be a list, but isn’t necessarily one.

Lists can be operated on with the list() command, which allows concatenating lists, searching them, accessing arbitrary elements and so on (documentation of ...

I am confused with a very simple example. I have a standard list, so basically its string representation uses semicolon as delimiters.

> cmake --help > cmake -G "Visual Studio 14 2015" .. If that doesn't help, try to set the Visual Studio environment variables first (the path could vary): > "c:Program Files (x86)Microsoft Visual Studio 14.0VCvcvarsall.bat" > cmake ..

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
