cmake refactor

[debris]

this pull request is enhancement of #87

if fixes the following

• building unit_testsuite in msvc
• building in Debug mode in msvc
• building dynamic libraries in Xcode generated project on macos
• fixes MACOSX_RPATH policy warning on macos
• include_directories are not included globally any more
• unifies CMake files style
  • use 4 spaces width tabs
  • variables use upper case
  • macros/functions use lower case
• separated parts of cmake logic
  • separated CMakeCompilerSettings.cmake
  • separated CMakeDependencies.cmake
• refactored FindXXX.cmake files
  • as far as i know, we do now have to add paths usr/include && usr/local/include, they should be searched by default
  • ${CMAKE_SOURCE_DIR}/win32-deps/ moved to CMAKE_PREFIX_PATH, so new cmake search paths are backwards compatible
  • FindJsoncpp.cmake don't generate any files. Instead it's using PATH_SUFFIXES to solve jsoncpp versions incompatibility.

changes:

• src/jsonrpccpp/CMakeLists.txt now installs all header files, if it is unwanted, we can remove them from the list by using list REMOVE_ITEM. I think it's much cleaner solution, than previous one.

Architecture of the library itself remained unchanged, i didn't want to create any incomatibilities with previous version

do we need these two lines in .travis.yml?

- g++ ../src/examples/simpleclient.cpp -ljsonrpccpp-client -ljsoncpp -ljsonrpccpp-common -lcurl -o sampleclient
- g++ ../src/examples/simpleserver.cpp -ljsonrpccpp-server -ljsoncpp -ljsonrpccpp-common -lmicrohttpd -o sampleserver

Yes. It should check if linking against the library without cmake is possible, after the library has been installed.

[debris]

are these changes ok for you?

[debris]

Great! Yes, I'm done :)

[cinemast]

Files were not included beacuse they are not part of the public API. Which makes it more easy to change internal functionality. Please revert that change, or use remove for all the others.

[debris]

changes :

• jsonrpc_header_server && jsonrpc_client_server are used by cmake add_library command. This allows all header files to be included into cmake generated project (like Xcode).
• jsonrpc_install_header_server && jsonrpc_install_header_client are used by cmake install command and are part of public API

update, i will fix travis build in a minute

I fixed issues. Can you review pull request again?

After a quick review, it looks good. I will try to build on other platforms. If everything is fine. I will merge it. Thanks again for your contribution 👍

[cinemast]

Aside that, everything looks fine. Don't forget to add yourself to the AUTHORS.md ;)

Great! I guess a lot of people will appreciate MSVC support. Thanks again.
