libcrypto not found

[AdityaGovardhan]

While trying to build avs sdk on Ubuntu Linux, libcrypto couldn't be linked because openssl itself was not sufficient. I had to install libssl-dev for the same. I am not sure if this is an issue but wanted to bring it to notice. I used this for reference: https://stackoverflow.com/questions/13811889/cannot-find-libcrypto-in-ubuntu

Thanks @AdityaGovardhan for bringing this to our attention. We do list our dependencies here, just fyi, but appreciate setup on different platforms may vary.

Adding for people who have future problems with this. Having the depencies out of the box will not ensure the setup for AVS will work. I had the same issue while running "cmake".
Error:
-- No package 'libcrypto' found.

I'm on Mac, and I have openssl which is their equivalent for libssl-dev. To fix this issue I had to use this: scipr-lab/libsnark#99 (comment)

After checking debian packages here, you can see that libssl-dev is not required but suggested. So libcurl4-openssl-dev provides curl.h and libssl-dev provides libcrypto.h. Thus the appropriate command would be sudo apt install libcurl4-openssl-dev libssl-dev

With later releases of AVS-SDK the libssl needs to be installed on Pi3 platforms and appears to be missing from the dependency list. Seems like I didn't have to do this with v1.7.1, but after upgrading to v1.13, it started throwing errors:

Creating the build directory for the PlaylistParser with build type: RELEASE Creating PlaylistParser with keyword detector type: Sensory Bluetooth implementation not supported -- Checking for module 'libcrypto' -- No package 'libcrypto' found CMake Error at /usr/share/cmake-3.7/Modules/FindPkgConfig.cmake:415 (message): A required package was not found Call Stack (most recent call first): /usr/share/cmake-3.7/Modules/FindPkgConfig.cmake:588 (_pkg_check_modules_internal) PlaylistParser/src/CMakeLists.txt:2 (pkg_check_modules)

Also, seems like after libssl-dev is installed you get a warning:

Installing 'libssl1.0-dev' makes the warning go away but I do not know if it's ok do this?
