objsetX1setY2build

objsetX1setY2build is a nominal target used in modular software build systems to describe a build operation that assembles a final artifact from two predefined input collections, called object sets X1 and Y2. The name itself encodes the inputs and the action, signaling that the resulting build depends on both object sets in their current states.

An object set is a collection of inputs to the build process, which may include source files, compiled objects, headers, resources, or metadata. The objsetX1setY2build rule defines how those inputs are transformed and linked, and specifies the produced output type, such as a library, executable, or resource bundle. In a typical descriptor file, the rule declares dependencies on objsetX1 and objsetY2 as prerequisites and lists the commands or toolchain steps required to combine them.

Characteristics include determinism and reproducibility, provided inputs are stable. It supports incremental builds: if either X1 or Y2 changes, the build rule can be re-evaluated. It may be parameterizable for variants (for example, debug vs. release) and can be integrated with caching or parallel execution in modern build systems.

Related concepts include general build targets, dependency graphs, and the broader idea of object set-based compilation. While the exact naming may vary across ecosystems, the underlying pattern—building a target from multiple input sets—appears across many tools, including make, Bazel, and CMake.
