* Clean up the CMake build system and improve the FindFFTW3 module. * Fixes for Linux build * Include winsock.h to get struct timeval * Couple more fixes for MSVC, also add new FindMath module * Update host build README for new CMake changes (esp. Windows) * Try to fix Travis OS X build error * Add docs about pthread-win32 * Whoops, AppVeyor caught a bug in FindFFTW where the includes not being found weren't generating a fatal error. * Travis rebuild bump * One more fix: replace hardcoded include paths with a PATH_SUFFIX to standard include paths * Invert Windows preprocessor flag so it's only needed when using a static build. This preserves compatibility with the previous system. * Fix copy-paste error * Update cmake modules from amber-cmake upstream, incorporate TryLinkLibrary into FindUSB1 * Fix missing include
