# - Find SWIG # This module finds an installed SWIG. It sets the following variables: # SWIG_FOUND - set to true if SWIG is found # SWIG_DIR - the directory where swig is installed # SWIG_EXECUTABLE - the path to the swig executable # SWIG_VERSION - the version number of the swig executable # # The minimum required version of SWIG can be specified using the # standard syntax, e.g. find_package(SWIG 1.1) # # All information is collected from the SWIG_EXECUTABLE so the # version to be found can be changed from the command line by # means of setting SWIG_EXECUTABLE # #============================================================================= # Copyright 2004-2009 Kitware, Inc. # Copyright 2011 Mathieu Malaterre # # 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.) find_program(SWIG_EXECUTABLE NAMES swig2.0 swig) if(SWIG_EXECUTABLE) execute_process(COMMAND ${SWIG_EXECUTABLE} -swiglib OUTPUT_VARIABLE SWIG_swiglib_output ERROR_VARIABLE SWIG_swiglib_error RESULT_VARIABLE SWIG_swiglib_result) if(SWIG_swiglib_result) if(SWIG_FIND_REQUIRED) message(SEND_ERROR "Command \"${SWIG_EXECUTABLE} -swiglib\" failed with output:\n${SWIG_swiglib_error}") else() message(STATUS "Command \"${SWIG_EXECUTABLE} -swiglib\" failed with output:\n${SWIG_swiglib_error}") endif() else() string(REGEX REPLACE "[\n\r]+" ";" SWIG_swiglib_output ${SWIG_swiglib_output}) # force the path to be computed each time in case SWIG_EXECUTABLE has changed. set(SWIG_DIR SWIG_DIR-NOTFOUND) find_path(SWIG_DIR swig.swg PATHS ${SWIG_swiglib_output}) if(SWIG_DIR) set(SWIG_USE_FILE ${CMAKE_ROOT}/Modules/UseSWIG.cmake) execute_process(COMMAND ${SWIG_EXECUTABLE} -version OUTPUT_VARIABLE SWIG_version_output ERROR_VARIABLE SWIG_version_output RESULT_VARIABLE SWIG_version_result) if(SWIG_version_result) message(SEND_ERROR "Command \"${SWIG_EXECUTABLE} -version\" failed with output:\n${SWIG_version_output}") else() string(REGEX REPLACE ".*SWIG Version[^0-9.]*\([0-9.]+\).*" "\\1" SWIG_version_output "${SWIG_version_output}") set(SWIG_VERSION ${SWIG_version_output} CACHE STRING "Swig version" FORCE) endif() endif() endif() endif() include(${CMAKE_CURRENT_LIST_DIR}/FindPackageHandleStandardArgs.cmake) FIND_PACKAGE_HANDLE_STANDARD_ARGS(SWIG REQUIRED_VARS SWIG_EXECUTABLE SWIG_DIR VERSION_VAR SWIG_VERSION )
