Missing Argon2 Library on Mint 18 (Based on Xenial)

[njfox]

I've been unable to build the develop branch from source on my Mint 18.2 machine for awhile now as there is no argon2 package available, even in the custom APT repo for some reason:

$ cat /etc/apt/sources.list.d/phoerious-keepassxc-xenial.list 
deb http://ppa.launchpad.net/phoerious/keepassxc/ubuntu xenial main
deb-src http://ppa.launchpad.net/phoerious/keepassxc/ubuntu xenial main

$ sudo apt-get install libargon2-0-dev

$ sudo apt-get install argon2

Here is the error from cmake:

CMake Error at /usr/share/cmake-3.5/Modules/FindPackageHandleStandardArgs.cmake:148 (message):
  Could NOT find Argon2 (missing: ARGON2_LIBRARIES ARGON2_INCLUDE_DIR)

  CMakeLists.txt:296 (find_package)

I've also made sure to update the package list with sudo apt-get update. Is there anything I'm missing here?

I had the same problem, see #1417. Unfortunately that issue has not been reopened, thoug.
I installed argon2 directly from github. Remeber to delete CMake cache.
@phoerious can you please update the wiki with my considerations made there (and a step on deleting cache as well)? It seems nevertheless that somehow the custom PPA failed to provide argon2 package. (see e.g. #1401). Should we investigate? I am available for testing out.

[phoerious]

The PPA only provides argon2 for Trusty. I'll upload a version for Xenial as soon as we get the beta out.

[phoerious]

PPA now provides argon2 for Xenial.

I've installed the argon2 package from the PPA on Xenial but I'm getting the following CMake error:

CMake Error at /usr/share/cmake-3.5/Modules/FindPackageHandleStandardArgs.cmake:148 (message):

Do I need to set environment variables pointing to the library or pass extra CMake options to build this?

[arichiardi]

I found that you need to pass the paths to cmake by -D. Not env vars. Afk now so I don't have an example, hopefully is clear.
