# - This module defines variables and macros required to build eCos application. # This file contains the following macros: # ECOS_ADD_INCLUDE_DIRECTORIES() - add the eCos include dirs # ECOS_ADD_EXECUTABLE(name source1 ... sourceN ) - create an eCos executable # ECOS_ADJUST_DIRECTORY(VAR source1 ... sourceN ) - adjusts the path of the source files and puts the result into VAR # # Macros for selecting the toolchain: # ECOS_USE_ARM_ELF_TOOLS() - enable the ARM ELF toolchain for the directory where it is called # ECOS_USE_I386_ELF_TOOLS() - enable the i386 ELF toolchain for the directory where it is called # ECOS_USE_PPC_EABI_TOOLS() - enable the PowerPC toolchain for the directory where it is called # # It contains the following variables: # ECOS_DEFINITIONS # ECOSCONFIG_EXECUTABLE # ECOS_CONFIG_FILE - defaults to ecos.ecc, if your eCos configuration file has a different name, adjust this variable # for internal use only: # ECOS_ADD_TARGET_LIB #============================================================================= # Copyright 2006-2009 Kitware, Inc. # # Distributed under the OSI-approved BSD License (the "License"); # see accompanying file Copyright.txt for details. # # This software is distributed WITHOUT ANY WARRANTY; without even the # implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. # See the License for more information. #============================================================================= # (To distribute this file outside of CMake, substitute the full # License text for the above reference.) # first check that ecosconfig is available find_program(ECOSCONFIG_EXECUTABLE NAMES ecosconfig) if(NOT ECOSCONFIG_EXECUTABLE) message(SEND_ERROR "ecosconfig was not found.
