Fails to find boost, while cmake-modules provides FindBoost.cmake; also fails to find jsoncpp

[yurivict]

It fails:

CMake Error at CMakeLists.txt:97 (find_package):
  Could not find a package configuration file provided by "Boost" with any of
  the following names:

    BoostConfig.cmake
    boost-config.cmake

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

while the file /usr/local/share/cmake/Modules/FindBoost.cmake exists. You should just use cmake-modules.

What OS do you use?

[yurivict]

FreeBSD

Try to drop the CONFIG option.

[yurivict]

@sizeofvoid I didn't set any config options.

[sizeofvoid]

I mean CONFIG in line 98

Now it can't find jsoncpp:

  Could not find a package configuration file provided by "jsoncpp" with any
  of the following names:

    jsoncppConfig.cmake
    jsoncpp-config.cmake

jsoncpp-1.8.1 provides jsoncpp.pc

# pkg info -l jsoncpp | grep pc
	/usr/local/libdata/pkgconfig/jsoncpp.pc

You are searching for a wrong .pc file.

[sizeofvoid]

find_package() is looking for CMake Modules and not *.pc files. jsoncpp doesn't offer any CMake modules. I think cpp-ethereum needs libjson-rpc-cpp which offers FindJsoncpp.cmake. cpp-ethereum` CMake builds environment hides all that information. Not really package maintainer friendly.

I have the same problem on a Mac. Removing CONFIG from the find_package(Boost) call gets me past the Boost problem. I installed libjson-rpc-cpp, but I still get the same jsoncpp error as yurivict.

[sizeofvoid]

I still run into the same cmake issues on non Linux OS. I quit my work on porting that software to OpenBSD.

in debian/ubuntu land running into the same issue...but was able to get past it with the changes in this branch. It's a bit of a work in progress but looks like boost/jsonrpc is included.
