PC_FFTW3f_FOUND indicates that FFTW3f was found via pkg-config.
It can also be found without pkg-config, if the necessary paths
are supplied. This fixes hackrf_sweep not being built in that case.
The libtarget variable isn't defined here (it's used in a helper
function above). This caused libhackrf to be built and installed without
a version number.
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.
Counter-intuitively, this actually saves us two cycles because we unroll
the first iteration of the loop that spins on the interrupt flag, saving
a branch in the case that the flag is clear the first time.
* Add artifact publish step for Windows libraries and host tools.
* Replace runner.workspace with github.workspace.
* Update checkout task to v4 to supress warning.
* Update CMAKE for libhackrf and hackrf-tools to also install DLLs on WIN32 platforms.
* Update uploadartifact task to v4 since v3 uses an end-of-life node version 16.
* Add a new windows variable for the vcpkg cmake toolchain makefile.
Compiling with clang-cl, gives this error:
```c
hackrf-tools/src/hackrf_sweep.c(685,3): error: call to undeclared function '_setmode'; ISO C99 and later do not support implicit function
declarations [-Wimplicit-function-declaration]
685 | _setmode(_fileno(stdout), _O_BINARY);
| ^
```
fixed by simply adding `#include <io.h>`.
* Call fftw_execute once prior to starting IQ streaming
* Add options to use/save to an FFTW wisdom file and specify plan
* Fix bug where using -P would also enable one-shot mode
Fixes#1366Fixes#1260
Addresses #863
* mask all signals in libhackrf transfer_threadproc
hackrf_transfer uses pause() and SIGALRM to print statistics and POSIX doesn't
specify which thread must recieve the signal, block all signals here, so we
don't interrupt their reception by hackrf_transfer or any other app which uses
the library (#1323)
* fix windows build and remove empty line
* Initial commit of hackrf_biast
* Cleaned up hackrf_biast
* Cleaned up usage info
* Include getopt.h for non-GNU systems
* Add support for overriding HackRF's default antenna power behavior in firmware. Add support for specifying antenna power behavior in libhackrf.
* Moved bias tee config routines into user_config.c, cleaned up operation of hackrf_biast
* hackrf_biast now calls usage() and exits when invoked with no arguments
* Fixed minor documentation error in usage()
* minor syntax cleanup
* Add some documentation to the host API call
* Add proper declaration magic in hackrf.h to hackrf_set_user_bias_t_opts() to appease Visual Studio
* Documentation changes suggested by @martinling
* Moved bias t setting above switch statement, removed line that explicit turned bias t off when entering OFF mode
* Change hackrf_set_user_bias_t_opts() to use a friendly struct() instead of a bitmask. User friendliness fixes to hackrf_biast options. More clang-format appeasement.
* Removed support for integer mode args from hackrf_biast
* clang-format error fixes
* Tweaked position of comment for clang-format v14
* Reformat files with clang-format v14 instead of 16
* Remove internal numeric modes for bias T settings
