That is a followup-to my commit last year:

| Try to fix my last revision about cmake_policy, with CMake-2.6.x
|
| CMake gives an error if one tries to use cmake_policy(VERSION x.y.z) if
| x.y.z is greater than the current CMake version.
|
| ------------------------------------------------------------------------
The following check:
if("${CMAKE_MAJOR_VERSION}.${CMAKE_MINOR_VERSION}" VERSION_GREATER 2.6)
is useless just after a call to:
cmake_minimum_required(VERSION 2.6.2)
The script used to fix that was:
#!/usr/bin/env perl
$replacement=<<'END';
if("${CMAKE_MAJOR_VERSION}.${CMAKE_MINOR_VERSION}.${CMAKE_PATCH_VERSION}" VERSION_GREATER 2.8.3)
cmake_policy(VERSION 2.8.4)
else()
cmake_policy(VERSION 2.6)
endif()
END
while(<>) {
if(/if\("\${CMAKE_MAJOR_VERSION}.\${CMAKE_MINOR_VERSION}" VERSION_GREATER 2.6\)/) {
while(<>) {
if(/^endif\(\)/) {
print "$replacement";
while(<>) {
print;
}
exit 0
}
}
}
print;
}
removed almost all occurenced (missing UseFiles). While
doing so, some CMakeLists.txt could also be simplified. In fact
many more CMakeLists.txt can be simplified, in one of two ways:
1) add external libs to CGAL_3RD_PARTY_LIBRARIES and
2) call cgal_create_single_source_program
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).
