REM This file is used only on Windows in order to install the FFTW library.
REM
REM Forward slashes in directory names must be converted to backslash in order
REM to work with xcopy. ARGH!
REM The first argument is the directory containing the extracted FFTW archive
REM The second argument is the directory that contains the prefix we are installing into.

REM Now convert the paths to use backslash and not forward slash
REM See http://www.dostips.com/forum/viewtopic.php?f=3&t=422

SETLOCAL EnableDelayedExpansion

REM Unpacking the FFTW archive produces this subdirectory which we will copy 
REM the header files from.

set source=%1
set source=!source:/=\!

set target=%2
set target=!target:/=\!

REM Now that the paths are Kosher, we can finally do what we came here for: 
REM Install the FFTW library.

if not exist %target%\lib mkdir %target%\lib
if not exist %target%\include mkdir %target%\include
if not exist %target%\bin mkdir %target%\bin

REM Produce libfftw3-3.lib from libfftw3-3.def
lib /def:%source%\libfftw3-3.def /out:libfftw3-3.lib
lib /def:%source%\libfftw3f-3.def /out:libfftw3f-3.lib
lib /def:%source%\libfftw3l-3.def /out:libfftw3l-3.lib

REM Install library, header and DLL
copy libfftw3-3.lib %target%\lib
copy libfftw3f-3.lib %target%\lib
copy libfftw3l-3.lib %target%\lib
copy %source%\fftw3.h %target%\include
copy %source%\libfftw3-3.dll %target%\bin
copy %source%\libfftw3f-3.dll %target%\bin
copy %source%\libfftw3l-3.dll %target%\bin
