Example. 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).

Thus, the following can be used inline to prepend all entries in a list: list (TRANSFORM FILES_TO_TRANSLATE PREPEND $ {CMAKE_CURRENT_SOURCE_DIR}) ...where FILES_TO_TRANSLATE is the variable name of the list.

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.)

CMake language Escape Sequences such as \t, \r, , and \\ may be used to construct literal tabs, carriage returns, newlines, and backslashes (respectively) to pass in a regex. For example: The quoted argument "[\t\r ]" specifies a regex that matches any single whitespace character.

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

One possibility is to add TRANSFORM sub-command with the following possible actions: APPEND , PREPEND : concatenate prefix or suffix; REPLACE : ...
