compilation issue

[ShawnshanksGui]

When I implement : conan install .. -s compiler=gcc -s compiler.libcxx=libstdc++11 --build=missing , I meet some problem:

CMake Error at 3rdparty/ippicv/downloader.cmake:77 (message):
ICV: Failed to download ICV package: ippicv_linux_20151201.tgz.
Status=1;"Unsupported protocol"

And after google, I guess that it may be due to the opencv installment's error, I just install opencv under the path: /360Transformations/transformation/build/ConanEnv , but it does'not work!!!

And my enviroment is :
ubuntu14.04
git version 2.15.0
gcc (Ubuntu 5.4.1-2ubuntu1~14.04) 5.4.1
python3.4
cmake 3.22

Would you help me to have a look at what's wrong?

Thanks!
