This repository contains a collection of CMake files that will be used to build sac2c packages. We are going to use this repository as a sub-module in the packages so that maintenance of the common part of the build system gets easier.

Individual files have the following functionality:

• check-sac2c.cmake checks whether we have an operational sac2c compiler. The SAC2C_EXEC variable overrides search for sac2c on the PATH. This produces the SAC2C_VERSION variable.

• sac2c-variables.cmake defines a number of useful sac2c variables that are mainly coming from parsing sac2crc for a given TARGET. Also it performs some sanity checks like: chosen target is set in sac2crc, sac2c executable is set, etc.

• generate-version-vars.cmake defined a function where generates the MAJOR, MINOR, and PATCH numbers using the git-describe tool.

• resolve-sac2c-dependencies.cmake defines a function that for a given file runs sac2c -M, checks whether external dependencies to the Tree and Mod shared libraries can be found; and generates a list of local dependencies that can be used while defining a custom target in CMake.

• generate-sac2c-dependency-targets.cmake provides a very similar function as is in resolve-sac2c-dependencies.cmake, with the main distinction being that instead of outputting module library file paths, it returns target names.

• generate-sac2crc-file.cmake is a script which is used to generate a sac2crc file for a package, called sac2crc.package.<package>. It places it into the user's home directory under .sac2crc directory. It is intended that the script is used as a target within the package build.

• check-sac2c-feature-support.cmake contains a collection of macros/functions which check for supported features in sac2c. The results are intended to be exposed via the generated config.h file.

• build-sac2c-module.cmake provides macros to create targets to build SaC modules (with dependency resolution provided by resolve-sac2c-dependencies.cmake)

• build-sac2c-progam.cmake provides macros to create targets to build SaC programs (with dependency resolution provided by resolve-sac2c-dependencies.cmake)

• sac2c-prog-with-versions.cmake provides macros to create targets to build SaC programs that make use of an external version config. Precise details of what this is is explained within the cmake file.

• misc-macros.cmake contains a miscellaneous collection of functions and macros. Further details on what these functions do is given as comments within.
