[Seqan-dev] SeqAn Build System Rewrite

["Holtgrewe, Manuel" <manuel.holtgrewe@fu-berlin.de>]

Dear all,

I have just committed an update to the SeqAn build system. The main visible changes are that the Release mode is now the default CMAKE_BUILD_TYPE such that people who just want to build a SeqAn application do not accidently build the debug version any more and that the binaries are now all copied to "bin/" in the build directory.

Other major changes are:

* The FindSeqAn.cmake module is now a real CMake module. This means you can use "find_package(SeqAn)" in your own CMake projects outside the SeqAn build system. You only have to copy over the file utils/cmake/FindSeqAn.cmake.

* It is now possible to generate project files/build systems for one application only. This makes it easier for us to release applications for multiple platforms and plays together nicely with our SVN restructuring.

* The SeqAn apps now use the FindSeqAn.cmake module.

The new system currently is backwards compatible with CMakeLists.txt files from the previous version so you can take some time switching over the sandbox. However, the legacy functions are deprecated and their support will be discontinued in the future.


You can see how a plain sandbox with the new build system looks like by using the updated code generator:

./util/bin/skel.py repository sandbox/example
./util/bin/skel.py module ex_module sandbox/example
./util/bin/skel.py test ex_module sandbox/example
./util/bin/skel.py app ex_app sandbox/example
./util/bin/skel.py demo ex_demo sandbox/example


There is documentation on the new build system in the SeqAn Wiki:

I hope this causes not too much inconvenience for you. If there is any problem for you then please report it to us and we will help you fix it.

Cheers,
Manuel
