From 0b7bc77e305d8d4bd5615e54cf61f32cd0cac9c2 Mon Sep 17 00:00:00 2001 From: Oscar Fuentes Date: Sat, 2 Apr 2011 13:21:12 +0000 Subject: [PATCH] Handle changing of LLVM_ENABLE_FFI. If someone first configure build with LLVM_ENABLE_FFI=1 and then turn it off, the build will fail in lib/ExecutionEngine/Interpreter because Interpreter will try still to #include , but there are no include_directories(${FFI_INCLUDE_DIR}) now. This patch unset()'s HAVE_FFI_H and HAVE_FFI_FFI_H from cache file if LLVM_ENABLE_FFI=0. This forces CMake to update config.h.
