Summary:                    [PATCH] FindRuby does not find ruby-1.9.1 shipped
with (k)ubuntu
Description: 
Hello,

FindRuby only found the 1.8.6 version of my ruby installation, even if I force
the RUBY_EXECUTABLE name.

Steps to Reproduce: 
install ubuntu
install both ruby1.8-dev and ruby1.9.1-dev

Use in cmake:

FIND_PACKAGE( Ruby REQUIRED )
SET( RUBY_EXECUTABLE "ruby1.9.1" )

It did not find the ruby library. because it misses a "-" and it does not use
full version. Also, RUBY_EXECUTABLE is not an common input. My config is kind of
a hack but the fix is still valid.

Additional Information: 
I did a patch to fix this issue when library is libruby-1.x.x.

I also noticed that there is both RUBY_MAJOR_VERSION and RUBY_VERSION_MAJOR. Is
it all right?

Also, some parameters use Ruby_XXX form instead of RUBY_XXX. I guess the default
in cmake should be the latter (but it will break previous uses).

At Last, if I have multiple ruby installations, I cannot simply set:

(Ruby_FIND_VERSION "1.9")

This should be the easiest solution. However, I'm no expert in cmake lang.
