[Bug] Native Jetson Orin (sm_87) build: explicit -DCMAKE_CUDA_ARCHITECTURES ignored + CuTe DSL --wrap/cudart shim not propagated to static-lib consumers

Describe the bug

On a native Jetson Orin (sm_87, JetPack 6 / CUDA 12.6) build — compiling on the device itself with -DEMBEDDED_TARGET=jetson-orin, not the aarch64 cross toolchain — two build-system issues prevent the project from building/linking out of the box. Impact: blocker for native Orin builds.

1. The top-level default CUDA architecture list clobbers an explicit -DCMAKE_CUDA_ARCHITECTURES.
CMakeLists.txt sets CMAKE_CUDA_ARCHITECTURES = 80;86;89[;100a;120] whenever AARCH64_BUILD is undefined. A native Orin build is not a cross build, so AARCH64_BUILD is unset and the datacenter arch list is forced even when the user configures with -DCMAKE_CUDA_ARCHITECTURES=87. The build then targets the wrong SM.

2. The CUDA<12.8 _cudaLaunchKernelEx wrap and the cutedsl cudart shim are not propagated to the final executable when CuTe DSL is linked through a STATIC_LIBRARY.
cmake/CuteDsl.cmake (cute_dsl_setup()) attaches the cutedsl cudart shim and -Wl,--wrap=_cudaLaunchKernelEx with PRIVATE. A static archive performs no link step, so for STATIC_LIBRARY link targets neither reaches the consuming executable, and the CuTe DSL GEMM path fails to link/resolve on JetPack 6 / CUDA 12.6 (wrapped _cudaLaunchKernelEx / cudaLibrary_t).

Steps/Code to reproduce bug

Build configuration:

# On a Jetson Orin (sm_87, JetPack 6 / CUDA 12.6), native (on-device) build:
cmake -B build -DCMAKE_BUILD_TYPE=Release \
  -DEMBEDDED_TARGET=jetson-orin \
  -DCMAKE_CUDA_ARCHITECTURES=87 \
  -DTRT_PACKAGE_DIR=/path/to/TensorRT
cmake --build build -j
# (1) Configure still resolves CMAKE_CUDA_ARCHITECTURES to 80;86;89 (+100a;120), not 87.
# (2) Linking the CuTe DSL static-library consumer fails on the wrapped _cudaLaunchKernelEx.

Expected behavior

• An explicit -DCMAKE_CUDA_ARCHITECTURES (e.g. 87) is respected; the project's default arch set applies only when the user does not provide one. Regular x86 builds are unchanged.
• The cutedsl cudart shim and the --wrap linker option reach the final executable when CuTe DSL is consumed via a static library, so JetPack 6 / CUDA 12.6 builds link.

System information (Edge Device)

• Platform: NVIDIA Jetson Orin
• Software release: JetPack 6 (CUDA 12.6)
• CPU architecture: aarch64
• GPU compute capability: SM87
• Build type: Release
• Library versions:
  • TensorRT Edge-LLM version or commit hash: v0.8.0 (f9cc746)
  • CUDA: 12.6
• CMake options used:
  • EMBEDDED_TARGET: jetson-orin
  • CMAKE_CUDA_ARCHITECTURES: 87

A fix is ready and will be submitted as a PR referencing this issue.

Start with CMakeLists.txt to trace how the default CUDA architecture list is selected, then inspect cmake/CuteDsl.cmake and cute_dsl_setup() for static-library link propagation. Reproduce the native Jetson Orin configuration with CUDA 12.6 and the provided CMake options. Done means an explicit architecture such as 87 is retained and the CuTe DSL static-library consumer links successfully.
