Global view of dependencies, so multiple build passes or reordering targets is not required. Ability to share built files in a cache to speed up multiple builds - like ccache but for any type of target file, not just C/C++ compilation
CMake ships with numerous .cmake script files and development tools that facilitate tasks such as finding dependencies (both built-in and external, e.g. FindXYZ modules), testing the toolchain environment and executables, packaging releases (CPack), and managing dependencies on external projects (ExternalProject module).
makedepend solves this problem by parsing the code of C source files to generate a list of dependencies (those header files included directly and indirectly). It is able to understand conditional compilation constructs so as to not generate excessive dependencies. It then appends rules expressing the dependencies to the Makefile.
Explicit rule: defines when and how to update a target, listing prerequisites (dependent targets) and commands that define the update action, called the recipe; Implicit rule: defines when and how to remake a class of files based on their names, including how a target depends on a file with a name similar to the target and an update recipe
Meson can automatically find and use external dependencies installed on the users system via pkg-config, CMake, and project-specific lookups. [18] Alternatively, or as a fallback, a dependency can be provided as a subproject – a Meson project within another, either contained or as a download link, possibly with patches. [ 19 ]
Bazel is extensible with the Starlark programming language. [13] Starlark is an embedded language whose syntax is a subset of the Python syntax. However, it doesn't implement many of Python's language features, such as the ability to access the file I/O, in order to avoid extensions that could create side-effects or create build outputs not known to the build system itself.
In object-oriented design, the dependency inversion principle is a specific methodology for loosely coupled software modules.When following this principle, the conventional dependency relationships established from high-level, policy-setting modules to low-level, dependency modules are reversed, thus rendering high-level modules independent of the low-level module implementation details.
A configure script configures a software package for installation on a particular target system. After running a series of tests on the target system, the configure script generates header files and a makefile from templates, thus customizing the software package for the target system.
