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 #]=======================================================================] # first check that ecosconfig is available find_program(ECOSCONFIG_EXECUTABLE NAMES ecosconfig) if(NOT ECOSCONFIG_EXECUTABLE) message(SEND_ERROR "ecosconfig was not found.
