    cmake and ci improvements · a8ae5b6e

    - ci: add build jobs for Debug/RelWithDebInfo on Bionic, as well as
      release builds on Xenial and El Capitan. Use templates to simplify
    - cmake: raise minimum version to 3.10
    - cmake: add workarounds to support macOS < 10.14
    - cmake: set ccache only if not yet set and print info
    - cmake: add NDEBUG define (to disable asserts) for release build and
      EIGEN_INITIALIZE_MATRICES_BY_NAN for others. Add externally supplied
      CMAKE_CXX_FLAGS at the end to allow overriding the defaults.
    - tests: add enable_testing() in main CMakeLists.txt, such that we can
      call 'ctest' from build folder.
    - tests: simplify gtest / gtest_main linking
    - tests: enabled benchmarks only on Linux with GCC (doesn't compile
      with clang)
    - tests: use the newer gtest_discover_tests instead of add_test, which
      adds a separate cmake test for every gtest, even with multiple
      defined in a single executable. Its not only more reliable and less
      verbose in the CMakeLists.txt, but also allows to run 'ctest'
      without -V and still see status for every individual test.
