Toolchain And Language Expressions ¶ Platform ¶ $ ¶ are evaluated using the custom command's "command config". With the Ninja Multi-Config generator, generator expressions Only valid in add_custom_command() and add_custom_target()Īs the outer-most generator expression in an argument. List() command, it is specific to the list-handling generator Since a comma is used to separate the list and the value, the listĬannot itself contain a comma. Must not contain any commas if that generator expression expects something toīe provided after the list. In each of the following list-related generator expressions, the list List() command, providing the same capabilities, but in Most of the expressions in this section are closely associated with the Same behavior as string(MAKE_C_IDENTIFIER). $ ¶Ĭontent of string converted to upper case.
