# C/C++ Properties, Build, Settings, Build Steps tab

Customizes the selected build configuration allowing for the specification of user defined build command steps, as well displaying a descriptive message in the build output, immediately before and after, normal build processing executes.

Note: To ensure reasonable custom build step behavior, sensible input must be provided when specifying custom build step information. Custom build steps are not verified for correctness in any regard and are passed exactly as entered into the build stream.
In the descriptive text, below, the term "main build" is defined as the sequence of commands to execute when a build is invoked, not including pre-build or post-build steps.

Pre-build Steps | Identifies any steps that are to occur before the build takes place. Note: The pre-build step is not executed if the state of the main build is determined to be up to date; otherwise it is executed. An attempt to execute the main build will occur regardless of the success or failure of executing the pre-build step.
Command | Specifies one or more commands to execute immediately before the execution of the build. Use semicolons to separate multiple commands.
Description | Specifies optional descriptive text associated with the pre-build step that is displayed in the build output immediately before the execution of the pre-build step command (or commands).
Post-build steps | Identifies any steps that are to occur after the build takes place. Note: The post-build step is not executed if the state of the main build is determined to be up to date. It will be executed only if the main-build has executed successfully.
Command | Specifies one or more commands to execute immediately after the execution of the build. Use semicolons to separate multiple commands.
Description | Specifies optional descriptive text associated with the post-build step that is displayed in the build output immediately after the execution of the post-build step command (or commands).
