I'm trying to build mkvtoolnix
My mkvtoolnix revision is 0fa1a9e4277858a1cb1bc071d19b092de1dfe409
My MXE revision is custom (master MXE + some tested commits).

*** git submodule init
*** git submodule update

$ host=i686-w64-mingw32.static
$ qtbin=/mxe/usr/${host}/qt5/bin
$ ./autogen.sh
$ ./configure --host=${host} -enable-qt --enable-static-qt
--with-mkvtoolnix-gui --with-moc=${qtbin}/moc --with-uic=${qtbin}/uic
--with-rcc=${qtbin}/rcc -with-boost=~/mxe-reorg-build-pkg/usr/${host}

...
checking for boostlib >= 1.46.0... yes
checking whether the Boost::System library is available... yes
configure: error: Could not find a version of the library!

^^^ Error in configure
