If those tests can read their input from any location keeping them in the 
source dir is the best you can do as you don't waste space and time by copying 
them.

If those input files need to be adapted for a test run, e.g. telling them the 
location of a path, the endianess, bit size, or a configuration option of the 
build you may want to have a look on configure_file(). If those scripts create 
any temporary files I think it's best to set their working dir 
(WORKING_DIRECTORY property or option) to the binary tree.  Be careful that 
those tests may be run in parallel if you run ctest -j, so make sure they 
either use different filenames or different directories.

set_tests_properties(... PASS_REGULAR_EXPRESSION)?
