Fix compilation with CMake 3.5
...
The CMake variables CMAKE_BINARY_DIR and CMAKE_SOURCE_DIR should never be set. Now CMake 3.5 prevents the user from doing that. They have been replaced by their counterparts PROJECT_BINARY_DIR and PROJECT_SOURCE_DIR

Fixing missing phase increment in SIMD implementations
...
After computing the rotation with SIMD instructions, we were not
incrementing the phase step, so the first iteration in the 'c region'
had the same phase than the last sample computed with SIMD instructions.
This commit fix the bux in SSE3 and NEON implementations
