link_directories(${sleef_BINARY_DIR}/lib)                 # libsleefquad
link_directories(${sleef_BINARY_DIR}/src/common)          # common.a
include_directories(${sleef_BINARY_DIR}/include)          # sleef.h, sleefquad.h
include_directories(${sleef_SOURCE_DIR}/src/quad)         # qrename.h
include_directories(${sleef_BINARY_DIR}/src/quad/include) # rename headers
```
