      fix(cmake): fix cmake depends · e4af4225
      由 Megvii Engine Team 提交于 
      reason: some target call python3 to generate some headers,
if PYTHON_EXECUTABLE changed, headers will be invalid, which
will lead to rebuild most of obj, because this headers will
be include in most cpp/c, what`s more, this target do not depends
python3 version(python API) the output is same when use python3.5
or python3.x so change use PYTHON_EXECUTABLE to
PYTHON3_EXECUTABLE_WITHOUT_VERSION, when
PYTHON_EXECUTABLE/PYTHON_LIBRARY/PYTHON_INCLUDE_DIR changed,
can reuse the build obj

      fix(build/lite): fix lite rc4_encryptor build failed at new ld env · 89e52281

      when cuda enable:

error log:
nn-8.0.4-trt-7.2.2.3-libs/TensorRT-7.2.2.3/lib/libnvinfer_static.a(profile.o):
undefined reference to symbol 'dlclose@@GLIBC_2.2.5'
/usr/bin/ld:
/usr/lib/gcc/x86_64-linux-gnu/9/../../../x86_64-linux-gnu/libdl.so:
error adding symbols: DSO missing from command line

ld version:
GNU ld (GNU Binutils for Ubuntu) 2.34, example ubuntu20.04

error reason: at new ld, import flags with active zone

libnvinfer_static.a depend dlclose@@GLIBC_2.2.5, which need -ldl

ld -o rc4_encryptor xxx.o -ldl libnvinfer_static.a, which failed

so we put a -ldl for CUDA_LIBS env, then will change to
ld -o rc4_encryptor xxx.o  libnvinfer_static.a -ldl

      由 Megvii Engine Team 提交于 
      * support arm-host and x86-cross-arm
* fix trt myelib cmake build issue at 'trt copy env'(about 'copy env', Please refs cb92123f)

about x86-cross-arm CUDA env:
1: run ./scripts/cmake-build/create_cuda_build_libs.py to prepare
   cuda/cudnn/trt env(download deb package info, Please refs create_cuda_build_libs.py)
2: export TRT_ROOT_DIR=xxxxx which may create by step 1
3: export CUDNN_ROOT_DIR=xxxx which may create by step 1
4: export PATH=xxxx:$PATH  xxxx need create by step 1, which nvcc have
   relative path dir: ../targets/sbsa-linux/

      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
