Proposed build instructions not working on Mac OS X 10.10

Both the make and make lines will produce errors on OS X (tested on Yosemite). 
If you run `cmake ..` from within build, you get: `CMake Error: The source 
directory "/Applications/sfntly" does not appear to contain CMakeLists.txt.`

sfntly Revision 239 on OS X 10.10 (14A389)

Here is what I did:
svn checkout http://sfntly.googlecode.com/svn/trunk/ /Applications/sfntly/
cd /Applications/sfntly/
mkdir build
cd build
cmake ..

Then I get the error. If I continue with …

cmake ../cpp

… but then I get this output:

-- The C compiler identification is AppleClang 6.0.0.6000054
-- The CXX compiler identification is AppleClang 6.0.0.6000054

-- Build files have been written to: /Applications/sfntly/build

Then I get this error from `make`:

make: *** No targets specified and no makefile found.  Stop.
