Summary:                    Ninja: -Wl, -rpath,'$ORIGIN/foobar' not working
correctly in CMAKE_EXE_LINKER_FLAGS
Description: 
I used the testcase from issue http://public.kitware.com/Bug/view.php?id=13069
and added to the CMakeLists.txt file below line 16:
SET(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -Wl,-rpath,'$ORIGIN/foo'")

Then I used the Ninja generator to generate the ninja build files and built it
using ninja 1.0.0.

Inspecting the resulting executable with "objdump -p flags" it shows: "RPATH
/foo"

Using the Makefile generator and building it with make gives the expected entry
shown by objdump: "RPATH $ORIGIN/foo".

Looking at the build.ninja file generated by cmake I see this line:
LINK_FLAGS = -Wl,-rpath,'$ORIGIN/unitTests'

Changing it to:
LINK_FLAGS = -Wl,-rpath,'$$ORIGIN/unitTests'
(double $$) gives the correct RPATH entry in the executable.

It seems as if there needs to be some escaping done with "$" signs when
generating build.ninjs files.
