pi@raspberrypi:~/fbcp-ili9341/build $ arch=x86_64 cmake -DSPI_BUS_CLOCK_DIVISOR=40 -DWAVESHARE_1INCH3_LCD_HAT=ON -DBACKLIGHT_CONTROL=ON -DSTATISTICS=0 ..
CMake Warning (dev) in CMakeLists.txt:
  No project() command is present.  The top-level CMakeLists.txt file must
  contain a literal, direct call to the project() command.  Add a line of
  code such as

    project(ProjectName)

  near the top of the file, but after cmake_minimum_required().

  CMake is pretending there is a "project(Project)" command on the first
  line.
This warning is for project developers.  Use -Wno-dev to suppress it.

-- Detected this Pi to be one of: Pi 2B rev. 1.2, 3B, 3B+, 3A+, CM3, CM3 lite, CM4 or 4B(1GB,2GB,4GB RAM), with 4 hardware cores and ARMv8-A instruction set CPU.
-- Enabling optimization flags that target ARMv8-A instruction set (Pi 2B >= rev. 1.2, 3B, 3B+, CM3 or CM3 lite)
-- Enabling fbcp-ili9341 backlight control
-- Scaling source image to view. If the HDMI resolution does not match the SPI display resolution, this will produce blurriness. Match the HDMI display resolution with the SPI resolution in /boot/config.txt to get crisp pixel perfect rendering, or alternatively pass -DDISPLAY_CROPPED_INSTEAD_OF_SCALING=ON to crop instead of scale if you want to view the center of the screen pixel perfect when HDMI and SPI resolutions do not match.
-- Preserving aspect ratio when scaling source image to the SPI display, introducing letterboxing/pillarboxing if HDMI and SPI aspect ratios are different (Pass -DDISPLAY_BREAK_ASPECT_RATIO_WHEN_SCALING=ON to stretch HDMI to cover full screen if you do not care about aspect ratio)
-- SPI_BUS_CLOCK_DIVISOR set to 40. Try setting this to a higher value (must be an even number) if this causes problems. Display update speed = core_freq/divisor. (on Pi3B, by default core_freq=400). A safe starting default value may be -DSPI_BUS_CLOCK_DIVISOR=40
-- USE_DMA_TRANSFERS enabled, this improves performance. Try running CMake with -DUSE_DMA_TRANSFERS=OFF it this causes problems, or try adjusting the DMA channels to use with -DDMA_TX_CHANNEL=<num> -DDMA_RX_CHANNEL=<num>.

This is a duplicate of #43. Note that fbcp-ili9341 works fine on a 64-bit kernel, it just needs to run as a 32-bit process. I'm not sure how to build a 32-bit application on 64-bit Raspbian, but I assume it's possible.
