Introduction to HIDAPI

The HIDAPI package provides a library for working with HIDs (Human Interface Devices) and can utilize libusb to better serve this goal.

Kernel Configuration

To allow HIDAPI to access HIDs, enable the following options and recompile the kernel if necessary: 

Device Drivers --->
  [*] HID bus support --->                                         [HID_SUPPORT]
    <*>   HID bus core support                                             [HID]
    [*]     /dev/hidraw raw HID device support                          [HIDRAW]
    <*/M>   User-space I/O driver support for HID subsystem               [UHID]
    <*>     Generic HID driver                                     [HID_GENERIC]

Installation of HIDAPI

Install HIDAPI by running the following commands: 

mkdir build &&
cd    build &&

cmake -D CMAKE_INSTALL_PREFIX=/usr   \
      -D CMAKE_BUILD_TYPE=Release    \
      -D CMAKE_SKIP_INSTALL_RPATH=ON \
      -W no-dev -G Ninja .. &&
ninja

Now, as the root user: 

ninja install

Command Explanations

-D CMAKE_SKIP_INSTALL_RPATH=ON: This switch makes cmake remove hardcoded library search paths (rpath) when installing a binary executable file or a shared library. This package does not need rpath once it's installed into the standard location, and rpath may sometimes cause unwanted effects or even security issues.
