- Remove TVM's `USE_CCACHE` option in favor
of CMake's built-in `CMAKE_C_COMPILER_LAUNCHER`
and `CMAKE_CXX_COMPILER_LAUNCHER` variables.
This eliminates a significant source of
complexity, especially:
- TVM's CI scripts, which use `sccache`
instead of `ccache`, and
- calls to `ExternalProject_add` in TVM's CMake logic.
- Ensure that `CMAKE_C[XX]_COMPILER_LAUNCHER` variables
are passed through in all `ExternalProject_add` calls.
- Update user documentation.
