平台：兆芯KX6640MA Deepin20
症状：

cmake -B build -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Release
执行后显示如下报错：

CMake Error at /usr/lib/cmake/clang-13/ClangConfig.cmake:11 (find_package):
Could not find a package configuration file provided by "LLVM" with any of
the following names:

LLVMConfig.cmake                                                                                          
llvm-config.cmake                                                                                         

Add the installation prefix of "LLVM" to CMAKE_PREFIX_PATH or set
"LLVM_DIR" to a directory containing one of the above files. If "LLVM"
provides a separate development package or SDK, be sure it has been
installed.
