7. Conditional Parts of Makefiles

A conditional causes part of a makefile to be obeyed or ignored depending on the values of variables. Conditionals can compare the value of one variable to another, or the value of a variable to a constant string. Conditionals control what make actually "sees" in the makefile, so they cannot be used to control shell commands at the time of execution.
