如何在cmake中通过SWIG更改生成的.py文件？

Question

我们可以使用EXECUTABLE_OUTPUT_PATH来类似于$ {PROJECT_BINARY_DIR} / bin。如何通过SWIG设置生成的python模块的输出路径。

例如，得到以下CMakeLists.txt

FIND_PACKAGE(SWIG)
IF(SWIG_FOUND) 
FIND_PACKAGE(PythonLibs)
IF(PYTHONLIBS_FOUND)

INCLUDE(${SWIG_USE_FILE})

EXECUTE_PROCESS( COMMAND python -c "import sys;print"%s.%s"%sys.version_info[0:2]" OUTPUT_VARIABLE PYTHON_VERSION OUTPUT_STRIP_TRAILING_WHITESPACE)


INCLUDE_DIRECTORIES(${PYTHON_INCLUDE_PATH})

INCLUDE_DIRECTORIES(${CMAKE_CURRENT_SOURCE_DIR})

SET(CMAKE_SWIG_FLAGS "")

SET_SOURCE_FILES_PROPERTIES(partio.i PROPERTIES CPLUSPLUS ON)
SET_SOURCE_FILES_PROPERTIES(partio.i PROPERTIES SWIG_FLAGS "-includeall")
SWIG_ADD_MODULE(partio python partio.i)
SWIG_LINK_LIBRARIES(partio ${PYTHON_LIBRARIES} ${ZLIB_LIBRARY} partio)

SET(PYTHON_DEST "lib64/python${PYTHON_VERSION}/site-packages" )
INSTALL(TARGETS _partio DESTINATION ${PYTHON_DEST})
INSTALL(FILES ${CMAKE_BINARY_DIR}/${outdir}/src/py/partio.py  DESTINATION ${PYTHON_DEST})

ENDIF(PYTHONLIBS_FOUND)
ENDIF(SWIG_FOUND)

从CMake 2.8 docs：

另一个特殊变量是CMAKE_SWIG_OUTDIR，它允许您指定将所有swig生成的模块写入何处（swig -outdir选项）

因此，例如：

set(CMAKE_SWIG_OUTDIR ${CMAKE_CURRENT_BINARY_DIR}/bin)
