How do you change the compiler used by the makefile according to the example?

Change the CPP variable
Install the new compiler in the system path
Rewrite the compiler invocation commands
Directly modify the compiler source code

The correct answer is: Change the CPP variable

When using a makefile, the CPP variable is responsible for specifying the compiler used for compiling code. By changing this variable, you can change the compiler used without having to rewrite the entire makefile or modify the source code. Options B and D are incorrect because they involve external actions that would not directly affect the makefile. Option C is incorrect because rewriting the compiler invocation commands would essentially be changing the makefile itself. Thus, the most efficient and effective way to change the compiler used by the makefile is to modify the CPP variable.
