1. A method comprising: setting, in a system comprising a processor, a build indicator in a build environment to a set value for building a program code, the set value selected from a first value indicating that a feature of the program code is enabled, and a second value indicating that the feature is disabled; setting, by the system, a build tool variable to a value indicating that the feature is enabled in response to the set value being the first value, and setting the build tool variable to a value indicating that the feature is disabled in response to the set value being the second value; setting, by the system, a runtime variable to a value indicating that the feature is enabled in response to the set value being the first value, and setting the runtime variable to a value indicating that the feature is disabled in response to the set value being second value; and building, by the system, the program code according to a value to which the build tool variable is set, wherein the program code comprises: a first portion supporting the feature used during execution of the program code in response to the runtime variable set to the value indicating that the feature is enabled, and a second portion without support for the feature used during execution of the program code in response to the runtime variable set to the value indicating that the feature is disabled.
