Buildroot commit [1] introduced a new Buildroot-Initialize.cmake file,
to mimic the upstream Linux-Initialize.cmake.
However, this upstream file was introduced in commit [2], which was
introduced in CMake 3.27.
When compiling a cmake package on a host with a cmake older than
version 3.27 (for example, the Buildroot Docker reference image has
cmake 3.25), the configuration fails with the error:
CMake Error at /buildroot/output/host/share/buildroot/Platform/Buildroot-Initialize.cmake:1 (include):
include could not find requested file:
Platform/Linux-Initialize
Call Stack (most recent call first):
/usr/share/cmake-3.25/Modules/CMakeSystemSpecificInitialize.cmake:21 (include)
CMakeLists.txt:20 (project)
CMake version < 3.27 is setting its LINUX predefine elsewhere (see
commit log of [1]), so this commit fixes the issue by simply making
the include optional. This will guarante thee cmake predefines will
be present in all the cases.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at https://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
