                 <b>LLDB_TEST_C_COMPILER</b> or <b>LLDB_TEST_CXX_COMPILER</b>: The test suite needs to be able to find a copy of clang.exe
                 that it can use to compile inferior programs.  Note that MSVC is not supported here, it <strong>must</strong> be a path to a
                 clang executable.  Note that using a release clang.exe is strongly recommended here, as it will make the test suite run much faster.
-                This can be a path to any recent clang.exe, including one you built yourself.

               Compiling with <code>ninja</code> is both faster and simpler than compiling with MSVC, but chances are you still want

               compiler, you can set the <strong>LLDB_TEST_C_COMPILER</strong> or the <strong>LLDB_TEST_CXX_COMPILER</strong> CMake variables.

               It is possible to customize the architecture of the test binaries and compiler used by appending -A
               and -C options respectively to the CMake variable <strong>LLDB_TEST_USER_ARGS</strong>. For
               example, to test LLDB against 32-bit binaries
