SCons-集成CUDA、CORBA等的自定义生成器

对于一个异构（C、C++14、Fortran95、python3）项目，我目前正在评估与CMake SCons相比，在集成CUDA（7.5）、CORBA（omniorb-4.2.1）、MPI2（MPICH）等平台编译器和编译器包装器方面将为我们提供哪些优势。

为了开始，我创建了一个项目根目录（附带SConstruct脚本中的"data/projects/snippets"），其中有一个子目录"model"，omnorb4 Documentation 的"echo.idl"

interface Echo { 
    string echoString(in string mesg); 
};

存在（带有int main()的echo_i.cc将由与-Wbexample开关一起使用的omniidl生成），以及子目录树"include/cuda_samples_inc"，它是cuda工具包示例的"common/inc"分支的副本，并复制cuda工具包样本

2_Graphics/simpleGL/simpleGL.cu 

到项目根目录中。

启用开关CUDA_PASS和CORBA_PASS时工作良好，但对于

CUDA = CUDAEnvironment()
o = CUDA.Object(['simpleGL.cu']) # line 63
CUDA.Program(o)

resp

CORBA = CORBAEnvironment()
skel = CORBA.Object(os.path.join('model', 'echo.idl'))  # line 98
impl = CORBA.Object('echo_i.cc')
CORBA.Program([skel, impl])

方块，烤饼由于我害怕的那种错误而放弃：

scons: *** While building `['simpleGL.o']' from `['simpleGL.cu']'
Don't know how to build from a source file with suffix `.cu'.  
Expected a suffix in this list: ['.c', '.m', '.cpp', '.cc', '.cxx', 
'.c++', '.C++', '.mm', '.C', '.f', '.for', '.ftn', '.fpp', '.FPP',
'.F', '.FOR', '.FTN', '.f77', '.F77', '.f90', '.F90', '.f95', '.F95',
'.f03', '.F03', '.s', '.asm', '.ASM', '.spp', '.SPP', '.sx', '.S'].
File "/data/projects/snippets/SConstruct", line 63, in <module>

分别：

scons: *** While building `['model/echo.o']' from `['model/echo.idl']':
Don't know how to build from a source file with suffix `.idl'
[same as above]
File "/data/projects/snippets/SConstruct", line 98, in <module>.

遗憾的是，

如何从后缀为<suffix> 的源文件构建

这正是我试图用我的定制环境和建设者告诉烤饼的。

所以我的问题是：

如何集成自定义环境和生成器，以便可以使用SCons Object()和Program()生成器立面

《苏格兰建设者》（）doc，特别是18.2。将生成器附加到构造环境似乎只是解释了我的PASS块中使用的语法以及传递的Program()调用，而不是如何使例如"Object（）"了解自定义生成器。

不用说，python本身可以用来编写几乎所有类型的行为或附加组件的代码，但我希望尽可能地留在SCons工具集的范围内。

版本：

SCons 2.3.1（但这在stone中并不可取，如果对2.4.1的更新会有所帮助，我会这么做）使用python 2.7.9 运行
