Summary:                    file(GENERATE) not processing variables from INPUT
file
Description: 
There is a bug when generating a file with:

file(GENERATE OUTPUT "${CMAKE_BINARY_DIR}/output1.txt" 
      INPUT ${CMAKE_SOURCE_DIR}/input.txt
)

file(GENERATE OUTPUT "${CMAKE_BINARY_DIR}/output2.txt" 
      CONTENT "SOURCE DIR = '${CMAKE_SOURCE_DIR}'"
)

- Using "INPUT filename", variables are not processed, but "CONTENT text" with
the same content works properly

Steps to Reproduce: 
1) cmake .
2) cat output1.txt
3) cat output2.txt

-> The variable in output1.txt is not replaced by its value
