What is the difference between the various preprocessor directives?
= | Assign new_value to VARIABLENAME |
: | Assign new_value to VARIABLENAME only if that variable does not already exist. |
+ | Append new_value to current value of VARIABLENAME. Uses a space as a separator. |
> | Append directory or file lists defined by new_value to a variable definition that defines a path. If no current value for VARIABLENAME exists, this is equivalent to the = operator. Otherwise, it appends a path separator character, a semicolon (;), and then new_value. |
< | "Prepend" directory or file lists defined by new_value (to the beginning of) a variable definition that defines a path. If no current value for VARIABLENAME exists, this is equivalent to the = operator. Otherwise, it prepends new_value followed by a path separator character, a semicolon (;). |
