Added script test_option which:
- compile and run without option
- compile with option given as argument, run
- diff on the two outputs, fails if different outputs
config file checks for existence of compiler (fails if not exist)
statics1.ept is a copy of statics.ept ; statics2.ept depends on statics1.ept
instead of statics.ept (so as dependency order => lexical order on file names)
Configuration files and scripts to perform tests with ctest
- ctest can be run into the test directory or the root
- the script CTestScript.cmake allows ctest to perform the whole
sequence update/configure/build/test and submit the result to
cdash (http://cdash.inria.fr/CDash/index.php?project=Heptagon)
- gen_ctests is used to generate the file test/CTestTestfile.cmake
