      fix(cmake/cuda): fix build at cuda `copy` env caused by b278a69e1 · 329306b0
      由 Megvii Engine Team 提交于 
      `copy` env vs `normal` env:
case a:`normal` env install CUDNN/TRT by package tool, eg, apt/yum, which
will put include file(cudnn.h/NvInfer.h) to /usr/include etc.

case b: self copy env after export CPATH with cudnn/trt include dir

case c: just copy libs, not export CPATH, only export
TRT_ROOT_DIR/CUDNN_ROOT_DIR

at case a and case b, BUILD system can find cudnn/trt headers, but
at case c, can not find. `FIX` it!

what`s more, recommend install CUDA env by case a and case c, NOT
recommend install by case b, which caused by CUDA SDK CPATH not
friendly to split c env, for example Android AOSP build env

      fix(cmake/whl): reduce wheel size · ae8b38f6
      由 Megvii Engine Team 提交于 
      as some reason: some version of trt/cudnn need
-Wl,--whole-archive attribute to fix cuda issue,
target A(CMAKE OBJECT,eg megbrain/megdnn): -Wl,--whole-archive depend on trt/cudnn
target B(SHARED LIBS,eg libmegengine.so) --> A with `PUBLIC` depends
target C(SHARED LIBS,eg _impertive.so) --> B with `PUBLIC` depends,
then ld will force link fatbin section into C, which will be undesired

what`s more, attribute PUBLIC/PRIVATE do not take effect
to OBJECT library(megbrain/megdnn)

what`s more, megengine/megengine_export have to PUBLIC for
mgb/imperative target, as SRC/include depends

so we pull cudalib depend from megbrain/megdnn to
megengine/megengine_export on linux os, to finall
target at windows os, for example lar on windows

      feat(build): install CMake config module and pkg-config descriptor · 786afef4
      由 Megvii Engine Team 提交于 
      Also, upgrade to CMake 3.13.

The commit also contains significant refactors, as otherwise it is not
possible to properly export target `megengine` to
MegEngine-targets.cmake:

1. Optionally use system provided Flatbuffers.
2. Optionally use system provided MKL-DNN (Tested with Debian).
3. Refactor megbrain and megdnn targets into object libraries.
4. Set different path in BUILD_INTERFACE and INSTALL_INTERFACE of
   various target_include_directories.
5. Specify PUBLIC/PRIVATE on various target_link_libraries.
