The module successfully found my Ruby 2.5.3 as-is, but the code in cmake's dev
branch only specifies up to 2.4. Adding as a precaution.
Also enabled _RUBY_DEBUG_OUTPUT for some handy debug output.
Edited the documentation block to not use reStructuredText... The
multi-line comment (beginning w/ '[[' & closing w/ ']]') requires cmake version
3 or greater.
Removed documentation block from FindPackageHandleStandardArgs + FindPackageMessage.
This handles newer distros with Ruby >1.8, e.g. config.h being at
ruby-2.5.0/config.h rather than ruby/config.h...
Also had to pull in some macros/functions as dependencies.
This is similar to #146 and fixes#148, #149, #150 and #153
When ruby is installed on the target machine, compile dislocker to have
bindings to it. This was done in the previous Makefile but not entirely
in the cmakelists toolchain.
