If you put this rule into a file called Makefileor makefileand then type makeon the command line it will execute the compile command as you have written it in the makefile. Note that makewith no arguments executes the first rule in the file.
One may also ask, Double-colon rules with the same target are in fact completely separate from one another. Each double-colon rule is processed individually, just as rules with different targets are processed. The double-colon rules for a target are executed in the order they appear in the makefile. Subsequently, A makefile is most often used as a build configuration file for a software project (or some part of a project's source code tree). It is used by the make program. The make program helps compile source code faster by not recompiling things that don't need to be recompiled. In fact, To create a makefile project in Visual Studio 2019 From the Visual Studio main menu, choose File > New > Project and type "makefile" into the search box. Accordingly, A makefile is a file (by default named "Makefile") containing a set of directives used by a make build automation tool to generate a target/goal . Most often, the makefile directs Make on how to compile and link a program.

Can a makefile be used by both gnu make and pmake?
This can lead to disastrous results when trying to write a Makefile that can be used by both GNU Make and pmake (contrived harmless example, imagine: gcc -o $@ $< = no input sources with gmake because $< evaluates to an empty string. Worse combinations exist that can result in gcc clobbering files). – Sean May 24 '11 at 19:27
