+Subject: [PATCH] CMake: Split static library exports into their own export
+ file
+
+Summary:
+This is to better support distros which split the static libraries into
+their own package.
+
+The current problem is that any project the includes LLVMConfig.cmake
+will fail to configure unless the static libraries are installed.  This
+is because LLVMConfig.cmake includes LLVMExports.cmake, which throws an
+error if it can't find files linked to one of the exported targets.
+
+This patch resolves the problem by putting the static library targets
+into their own export file, LLVMStaticExports.cmake.  This file
+is optionally included by LLVMConfig.cmake, so distros can put this
+new file in their static library package to make  LLVMConfig.cmake
+no longer depend on these libraries when they are not installed.
