We declare
cmake_minimum_required(VERSION 2.6.2)
but we also use
cmake_policy(VERSION 2.8.4)
to declare that our CMake scripts are OK with all the defaults of CMake policies
as of CMake-2.8.4. That shuts down the warnings of CMake-2.8.4.
That way, we no longer need any declaration of specific policies.
Those two lines must be present and maintained in all our CMakeLists.txt
files (the one for the libraries, and also the one for examples and demos,
and maybe tests).
The documentation of CGAL says that the minimal version of CMake must be
CMake-2.6.2.
- change cmake_minimum_required to VERSION 2.6.2
- no longer any need for the policy CMP0003 (was for 2.4.x)
- no longer any need for CMAKE_ALLOW_LOOSE_LOOP_CONSTRUCTS (was for 2.4)
CGAL 3.5 will include TAUCS/BLAS/LAPACK precompiled libraries for Visual C++ 8.0 and 9.0.
Auto-link is modified accordingly.
* Also fixed compatibility of cgal_test_with_cmake.bat scripts with VC++ 9.0.
Removed _HAS_ITERATOR_DEBUGGING=0 setting to go back to default settings.
This setting could create conflicts with third party libraries like _SECURE_SCL=0 crashes boost program options.
Note that no conflict with _HAS_ITERATOR_DEBUGGING was reported. This is just a safety change.
Fixed link with Boost.ProgramOptions on Windows/VC++
- Code cleaning:
CGAL_USE_TAUCS #define has been moved back to CGAL_UseTAUCS.cmake
- Added back traces of third-party libraries found.
FindBLAS.cmake and FindLAPACK.cmake in CMake 2.6.
The result is more or less equivalent to install_cgal's behavior.
TODO:
- use a C++ compiler instead of a Fortran one
- try to be compatible with CMake 2.4
- find CBLAS (http://www.netlib.org/cblas)?
Jet_fitting_3 and Surface_mesh_parameterization compile now with CMake
(tested on Linux/gcc and Windows/VC++ 2005).
Enforced CGAL_NDEBUG rule:
- code under include/CGAL/ and src/ must not use NDEBUG and assert(), but CGAL_NDEBUG and CGAL assertion macros.
- code under demo/, examples/ and test/ must use NDEBUG and assert().
- there is a clear distinction between internal errors (aka bugs) and not supported input files (typically models which are not topological discs),
- internal errors trigger a test suite failure.
The main consequence is that OpenNL errors trigger now a test suite failure.
in order to catch input meshes that do not respect them and avoid crashes in Release mode:
- For fixed border parameterizations:
Preconditions:
check that the border is mapped onto a convex polygon.
check that the input mesh is triangular (expensive check).
check that the input mesh is a surface with one connected component (expensive check).
Postconditions:
check one-to-one mapping.
- For free border parameterizations:
Preconditions:
check that the input mesh is triangular (expensive check).
check that the input mesh is a surface with one connected component (expensive check).
Postconditions:
check one-to-one mapping.
