Independent tests (#665) * Make tests buildable independently This makes "tests" buildable as a separate project that uses find_package(pybind11 CONFIG) when invoked independently. This also moves the WERROR option into tests/CMakeLists.txt, as that's the only place it is used. * Use Eigen 3.3.1's cmake target, if available This changes the eigen finding code to attempt to use Eigen's system-installed Eigen3Config first. In Eigen 3.3.1, it exports a cmake Eigen3::Eigen target to get dependencies from (rather than setting the include path directly). If it fails, we fall back to the trying to load allowing modules (i.e. allowing our tools/FindEigen3.cmake). If we either fallback, or the eigen version is older than 3.3.1 (or , we still set the include directory manually; otherwise, for CONFIG + new Eigen, we get it via the target. This is also needed to allow 'tests' to be built independently, when the find_package(Eigen3) is going to find via the system-installed Eigen3Config.cmake. * Add a install-then-build test, using clang on linux This tests that `make install` to the actual system, followed by a build of the tests (without the main pybind11 repository available) works as expected. To also expand the testing variety a bit, it also builds using clang-3.9 instead of gcc. * Don't try loading Eigen3Config in cmake < 3.0 It could FATAL_ERROR as the newer cmake includes a cmake 3.0 required line. If doing an independent, out-of-tree "tests" build, the regular find_package(Eigen3) is likely to fail with the same error, but I think we can just let that be: if you want a recent Eigen with proper cmake loading support *and* want to do an independent tests build, you'll need at least cmake 3.0.

Independent tests (#665) * Make tests buildable independently This makes "tests" buildable as a separate project that uses find_package(pybind11 CONFIG) when invoked independently.

In Eigen 3.3.1, it exports a cmake Eigen3::Eigen target to get dependencies from (rather than setting the include path directly). If it fails, we fall back to the trying to load allowing modules (i.e. allowing our tools/FindEigen3.cmake).
