Disabling Hunter is broken

[EoD]

Disabling hunter is broken in any of the current version (0.13, 0.12, ...)

The following sed magic is required to compile ethminer:
https://github.com/reagentoo/gentoo-overlay/blob/8b95566dc7ce7a81cbaa8183e664b3f036b8b31b/net-p2p/ethminer/ethminer-9999.ebuild#L51-L80

I already mentioned this before (#219), but I urge you to provide a way to completely disable hunter, without using Hunter. Hunter is the current blocker which keeps inclusion in the distributions like Gentoo: reagentoo/gentoo-overlay#6

[chfast]

Finding Boost works in master.

But I have problems with jsoncpp: libjson-rpc-cpp will find jsoncpp but include path is not compatible with libstratum. Anyway, you can try it in Gentoo, maybe you have a newer version os jsoncpp and it will work...

[EoD]

@chfast thanks, I tried dev-cpp/libjson-rpc-cpp-1.0.0 and dev-cpp/libjson-rpc-cpp-1.1.0 without success. Both now give the following error:

[chfast]

Yes, libjson-rpc-cpp::server is missing in libjson-rpc-cppConfig.cmake file. Easy fix.

But you can disable API module: -DAPICORE=OFF for now.

[EoD]

@chfast building with -DAPICORE=OFF passes the cmake phase, but fails the compilation phase:

[chfast]

Yes, I have the same problem. I can fix it but need to find some time to do it.

[ob7]

hows it coming? anyway to get this working without hunter? trying to build on nixos with same problem

[EoD]

@chfast do you have a commit or a small changelog what you did? Last time I checked, it did not build without hunter at all.

[chfast]

I don't plan to work on this. You can take it over.

[mratsim]

I've been trying to compiler ethminer on Archlinux and was also confronted with the following issue:

-- [cable ] Cable 0.2.12 initialized
-- [cable ] Build type: Release
-- Boost version: 1.68.0
-- Found the following Boost libraries:
--   system
--   filesystem
CMake Error at CMakeLists.txt:60 (find_package):
  Could not find a package configuration file provided by "jsoncpp" with any
  of the following names:

    jsoncppConfig.cmake
    jsoncpp-config.cmake

  Add the installation prefix of "jsoncpp" to CMAKE_PREFIX_PATH or set
  "jsoncpp_DIR" to a directory containing one of the above files.  If
  "jsoncpp" provides a separate development package or SDK, be sure it has
  been installed.


-- Configuring incomplete, errors occurred!

After diving a bit into it, the main cause is that on Arch (and probably many other distros) compilation of jsoncpp now uses Meson and Ninja.

Jsoncpp only registers itself to the CMake registry with jsoncppconfig.cmake if it's compiled by CMake which is not the default anymore see: open-source-parsers/jsoncpp#627.

The flag that enables jsoncpp in cmake is there: https://github.com/open-source-parsers/jsoncpp/blob/2baad4923e6d9a7e09982cfa4b1c5fd0b67ebd87/CMakeLists.txt#L12

OPTION(JSONCPP_WITH_CMAKE_PACKAGE "Generate and install cmake package files" ON)

but it is not available in meson.build
