Avoid linking LLVM component libraries with libLLVM Patch by Jack Howarth. When linking to libLLVM, don't also link to the component libraries that constitute libLLVM. Differential Revision: http://reviews.llvm.org/D16945 llvm-svn: 260641 2016-02-12 09:42:43 +08:00

[cmake] Export gtest/gtest_main and its dependencies via a special build tree only cmake exports file. Previously, gtest/gtest_main were not exported via cmake. The intention here was to ensure that users whom are linking against the LLVM install tree would not get the gtest/gtest_main targets. This prevents downstream projects that link against the LLVM build tree (i.e. Swift) from getting this dependency information in their cmake builds. Without such dependency information, linker issues can result on linux due to LLVMSupport being put before gtest on the linker command line. This commit preserves behavior that we want for the install tree, while adding support for the build tree by: 1. The special casing for gtest/gtest_main in the add_llvm_library code is removed in favor of a flag called "BUILDTREE_ONLY". If this is set, then the library is communicating that it is only meant to be exported into the build tree and is not meant to be installed or exported via the install tree. This part is just a tweak to remove the special case, the underlying code is the same. 2. The cmake code that exports cmake targets for the build tree has special code to import an additional targets file called LLVMBuildTreeOnlyExports.cmake. Additionally the extra targets are added to the LLVMConfig.cmake's LLVM_EXPORTED_TARGETS variable. In contrast, the "installation" cmake file uses the normal LLVM_EXPORTS_TARGETS as before and does not include the extra exports file. This is implemented by defining/undefining variables when performing a configure of the build/install tree LLVMConfig.cmake files. llvm-svn: 281085 2016-09-10 03:45:34 +08:00
