# How does it work?
# 1. We run the `ctest` program and ask it run "${CMAKE_CURRENT_SOURCE_DIR}/tools/CompileFailTest/CMakeLists.txt"
# with SOURCE=${sourcefile}.
# 2. CMake will then create a corresponding Makefile to compile ${sourcefile}.
# 3. `ctest` will then run this Makefile, the compilation should fail now (that's what we want to test)
# 4. with Set_Tests_Properties("${testname}" PROPERTIES WILL_FAIL ON)
# we told CTest (not the program! the current CMakeFile build target!) that we want the test named "${testname}"
# to fail, so it gets marked as "Passed" in summary
# @brief A macro for compile fail test (to test illegal code)
# based on Boost's BoostTesting.cmake
# URL: http://svn.boost.org/svn/boost/branches/CMake/Boost_1_35_0/tools/build/CMake/BoostTesting.cmake
