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.
