 Summary of the bug:
 I am trying to generate the libraries binaries for windows from Linux
 (Ubuntu 16.04). In order to so, I am using the mingw cross-compiler. The
 libraries are correctly generated in the build step (the .dll and .dll.a
 files), but in the install step I go this error:

 {{{
 LD      libavcodec/avcodec-57.dll
 LD      libavformat/avformat-57.dll
 LD      libavfilter/avfilter-6.dll
 INSTALL libavfilter/avfilter.dll
 STRIP   install-libavfilter-shared
 INSTALL libavfilter/avfilter.dll
 install: cannot stat 'libavfilter/avfilter.lib': No such file or directory
 library.mak:93: recipe for target 'install-libavfilter-shared' failed
 make: *** [install-libavfilter-shared] Error 1
 }}}

 How to reproduce:
 {{{
 1) Clone project
 2) Run configure:
 # ./configure --enable-pic --enable-shared --disable-static --disable-
 symver --disable-ffplay --disable-ffprobe --disable-devices --disable-
 avdevice --disable-nonfree --disable-gpl --disable-doc --enable-avresample
 --enable-demuxer=rtsp --enable-muxer=rtsp --disable-bzlib --disable-
 programs --disable-swresample --cc=/usr/bin/x86_64-w64-mingw32-gcc
 --cxx=/usr/bin/x86_64-w64-mingw32-g++ --prefix=/tmp --arch=x86 --target-
 os=mingw32 --enable-cross-compile
 3) make -j4
 4) make install
 }}}

 Am I missing something in the configuration step?
