Since the tests take a while to compile and link, and install depends
on all, users would have to build the tests even if they don't need
them. Create a new "check" target that has the tests in it, and remove
the tests from all.
This change removes prepare-depends.sh and Makefile, replacing it with
a CMake-based build system and git submodules of the needed
dependencies.
Notably, this simplifies the build of libsnark to be just
git clone --recursive git://github.com/scipr-lab/libsnark.git
cd libsnark
mkdir build && cd build && cmake .. && make
Since CMake also supports Ninja (apt-get install ninja-build on Debian
and derivatives), an even faster build could be obtained by using
cmake -GNinja .. && ninja
README.md has been updated to reflect the new build system.
All options supported by the Makefile are also supported by the CMake.
As an added benefit, users of libsnark can embed libsnark as a git
submodule and add it to their CMakeLists.txt, without having to
install it.
This change is a rebase of the earlier patch sent to the scipr-lab
developers, updated for new features introduced since then.
