1/ A compilation bug: in C++03, the constructor of std::ifstream cannot
take a std::string as filename argument. That constructor is available only
from C++11.
2/ The paths to the data files were wrong.
3/ Remove the useless commited cgal_test_with_cmake! As a matter of fact,
read_test.cpp was never tested by the daily testsuite because that file
cgal_test_with_cmake was commited and unmaintained.
