xbmgmt2: configure fails with -DXRT_EDGE=ON due to wrong target variable

[talhaHavadar]

Summary

src/runtime_src/core/tools/xbmgmt2/CMakeLists.txt references the wrong CMake variable in its XRT_EDGE branch, causing the configure step to fail for any build that sets -DXRT_EDGE=ON. The non-edge / native PCIe build path is unaffected. Reproduced against current master as well as the 202610.2.23.0_Canonical tag.

Reproduction

Configure XRT with XRT_EDGE enabled — anything that exercises the edge build path triggers it. Minimal repro on a native arm64 host (also reproduces via cross-compile or by manually forcing -DXRT_EDGE=ON):

$ cmake -S src -B build -DXRT_EDGE=ON -DXRT_AIE_BUILD=ON
...
-- add_subdirectory(xbmgmt2)
CMake Error at xrt/XRT/src/runtime_src/core/tools/xbmgmt2/CMakeLists.txt:68 (target_compile_definitions):
  Cannot specify compile definitions for target "PRIVATE" which is not built
  by this project.

Root cause

src/runtime_src/core/tools/xbmgmt2/CMakeLists.txt:68:

if (NOT XRT_EDGE)
  target_compile_definitions(${XBMGMT2_NAME} PRIVATE ENABLE_NATIVE_SUBCMDS_AND_REPORTS)
else()
  target_compile_definitions(${XBUTIL2_NAME} PRIVATE ENABLE_DEFAULT_ONE_DEVICE_OPTION)
endif()

XBUTIL2_NAME is set in the sibling src/runtime_src/core/tools/xbutil2/CMakeLists.txt:63 (set(XBUTIL2_NAME "xrt-smi")) — that's a directory-local scope and is not visible inside xbmgmt2/. In this scope the variable expands to an empty string, and CMake parses the call as target_compile_definitions(PRIVATE ENABLE_DEFAULT_ONE_DEVICE_OPTION), which fails because there's no target name.

The if (NOT XRT_EDGE) branch on line 66 correctly uses ${XBMGMT2_NAME}, so this looks like a copy/paste from xbutil2/CMakeLists.txt:78 where the variable rename was missed.

Impact

• Any configure with -DXRT_EDGE=ON fails before generation completes — the build doesn't produce xbmgmt, xrt-smi, or any other target in runtime_src.
• Native PCIe builds (-DXRT_EDGE unset / OFF) are not affected: the else-branch isn't entered.
• Affects current master and the 202610.2.23.0_Canonical release tag (and presumably every earlier release where the XRT_EDGE branch existed in this file).

Environment

• Distro: Ubuntu 26.04 LTS (arm64)
• CMake: 4.1.2
• XRT tag: 202610.2.23.0_Canonical (also reproduced on master HEAD)
• Reproducer: cmake -DXRT_EDGE=ON -DXRT_AIE_BUILD=ON (sbuild / native build, no cross-compile required to trigger the configure-time error)

Reported while packaging XRT for Ubuntu (source package xrt).
