sub-build.cmake:

CMake occasionally requires sub-builds in order to generate certain types of information. The sub-build mechanics are implemented in this file. This includes the ability to setup targets, builds, and handle information passing back and forth between the modules.

This file runs CMake on fprime, but registering only a set of target: (e.g. fpp_locs that do the work on the build. This allows CMake to generate build information to be consumed at the generate phase while maintaining the efficiency of properly expressed builds.

Function run_sub_build:

Runs a sub-build with the supplied SUB_BUILD_NAME. Output is set in PARENT_SCOPE to the name variable named by OUTPUT. The targets registered and run as part of the sub-build are supplied in ARGN.

Targets specified in ARGN must define top-level global targets in-order for the sub-build target to build correctly. Defining a no-op global target will result in only the generate step performing any useful actions, which may, in some cases, be desired.

SUB_BUILD_NAME: name of the sub-build and directory to contain its build cache JOBS: number of jobs to use in sub-build ARGN: list of targets to run as part of this sub-build. These will be registered, and run in order.

Function _get_call_properties:

Gets a list of properties to send to the call based on the values of these properties in the current build. This will set CALL_PROPS in PARENT_SCOPE and is only intended to be run from within the ,
