Refactor HackRF build system with a more modern CMake style.
Install files to allow library users using CMake to
find_project(HackRF CONFIG) and obtain HackRF::hackrf
and/or HackRF::hackrf_static library targets.
Add options ENABLE_STATIC_LIB and ENABLE_SHARED_LIB
to allow shared or static library to be disabled.
(Default builds both shared and static libraries.)
Add option ENABLE_HACKRF_SWEEP, when disabled allows
building without FFT library. (Default enabled.)
Add option DISABLE_USB_DEVICE_DISCOVERY for a compile definition
which could be used to alter libusb usage as needed on Android.
This adds a `hackrf_debug [-S|--state]` option, and the necessary
plumbing to libhackrf and the M4 firmware to support it.
The USB API and libhackrf versions are bumped to reflect the changes.
* 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
