Thanks for this package submission! Unfortunately, I'm afraid there is
an issue: it downloads stuff during the configure step. See below:

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.

Also, while note related to clpeak, I did try to build this
configuration (which uses the NXP OpenCL provider):

BR2_aarch64=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_BOOTLIN=y
BR2_TOOLCHAIN_EXTERNAL_BOOTLIN_AARCH64_GLIBC_STABLE=y
BR2_INIT_NONE=y
BR2_SYSTEM_BIN_SH_NONE=y
# BR2_PACKAGE_BUSYBOX is not set
BR2_PACKAGE_CLPEAK=y
BR2_PACKAGE_FREESCALE_IMX=y
BR2_PACKAGE_FREESCALE_IMX_PLATFORM_IMX8=y
BR2_PACKAGE_IMX_GPU_VIV=y
# BR2_TARGET_ROOTFS_TAR is not set

and it fails with:

/home/thomas/projets/buildroot/output/host/opt/ext-toolchain/bin/../lib/gcc/aarch64-buildroot-linux-gnu/9.3.0/../../../../aarch64-buildroot-linux-gnu/bin/ld: /home/thomas/projets/buildroot/output/host/aarch64-buildroot-linux-gnu/sysroot/usr/lib64/libGAL.so: undefined reference to `stat@GLIBC_2.33'

And indeed the C library in this toolchain is glibc 2.31. So this means
that the libGAL library shipped by NXP in imx-gpu-viv will only work
with glibc >= 2.33.

Best regards,

Thomas
