[CMake] Best way to copy Python test file to binary directory?

[James Amundson]

Hi,

I have a mixed C++/Python project. The test suite includes executing 
python files through a wrapper script. For example,

add_test(test_parallel_utils_py ${SYNERGIA2_BINARY_DIR}/synergia-local 
-c "import nose; nose.main()"
     test_parallel_utils.py)


One detail is important: the python file must exist in the binary 
directory. For reasons beyond my control, simply specifying the source 
directory as the location for test_parallel_utils.py won't work. For 
in-source builds, of course there is no problem -- the python file is 
already there.

What is the best way to get the python file into the binary directory 
for out-of-source builds?

Thanks for any advice,
Jim Amundson
