Altered CMakeLists.txt specifically for Mac OS Sierra 10.12.6

Hi Daniel,

I made PR as suggested. The CMakeLists.txt no longer has the static portion. I followed the install instructions - it installs just fine with the exception of a few Warnings. I have provided a screen shot to show the warnings.

Hey! We still want to compile statically on other platforms, so please apply this change :)

if(NOT APPLE)
    set(CMAKE_EXE_LINKER_FLAGS "-static")
endif()

Oh! I see. Thanks!

Hey Daniel,

Messing around in Vim today with rpp. What is the ideal text editor to work with rpp?

For example, I follow the "Hello World" example and this is what appears in Vim:
פלוט 'שלום עולם'

When ./rpp testHello.rpp is ran, I get the following result:
םלוע

Hey, from my checks the only usable code editor for rpp is notepad++, which you can flip so it will be right-to-left

BTW, do you want to fix this PR so I'll merge it?
