## Rules for building a program target

|
## The following variables must be passed when calling this file:
|
|
##
|
|
## BASE_DIR - base directory of the build system
|
|
## REP_DIR - source repository of the program
|
|
## PRG_REL_DIR - directory of the program relative to 'src/'
|
|
## REPOSITORIES - repositories providing libs and headers
|
|
## INSTALL_DIR - installation directory for stripped executables
|
|
## DEBUG_DIR - installation directory for unstripped executables
|
|
## VERBOSE - build verboseness modifier
|
|
## VERBOSE_DIR - verboseness modifier for changing directories
|
|
## VERBOSE_MK - verboseness of make calls
|
|
## SHARED_LIBS - shared-library dependencies of the target
|
|
## ARCHIVES - archive dependencies of the target
|

## LIB_CACHE_DIR - library build cache location
