# - Find the FFTW library

|

# The following variables will be checked by the function
|

|
|
# FFTW_USE_STATIC_LIBS ... if true, only static libraries are found

|
|
# FFTW_ROOT ... if set, the libraries are exclusively searched
|
||

|
# under this path
|
||

|
# FFTW_LIBRARY ... fftw library to use

# FFTW_INCLUDE_DIR ... fftw include directory
