Ralf W. Grosse-Kunstleve 774b5ff90b Removing obsolete eigen.h warning suppression pragmas. (#3198) ... * Removing all pragma from eigen.h * Removing -Werror or equivalent from tests/CMakeLists.txt * Restoring tests/CMakeLists.txt from master. * Adding 4 PYBIND11_SILENCE_MSVC_C4127. * Compatibility with -Wconversion, -Wdeprecated * Introducing PYBIND11_COMPATIBILITY_WDEPRECATED_COPY * Systematically using --verbose for compilations where possible (cmake 3.14 or newer). Also changing all `cmake -t` to `--target`, `-v` to `--verbose`, `check` to `pytest`, for consistency (to make it easier to pin-point all commands of a certain type). Also removing one `-j 2` for `pytest` in hopes of reducing flakes due to races in test_iostream and in prints from destructors. * Commenting out pragmas as an experiment to reproduce previous observation. * Removing all (newly added, but already commented-out) pragma code, adding HINT use -isystem (as cmake does). * Restoring ci.yml from master. Those changes are better handled separately. BTW: in the last CI run there was still a test_iostream flake, even without the -j 2 for running the tests (verfied by inspecting the log).		2021-08-17 16:49:39 -07:00
