# Experimental CMake build script for Google Test.
#
# Consider this a prototype. It will change drastically. For now,
# this is only for people on the cutting edge.
#
# To run the tests for Google Test itself on Linux, use 'make test' or
# ctest. You can select which tests to run using 'ctest -R regex'.
# For more options, run 'ctest --help'.

Move all of the GoogleTest files back to the same locations they occupy externally to simplify our integration of GoogleTest into LLVM. Also, build the single source file gtest-all.cc instead of the individual source files as we don't expect these to change and thus gain nothing from increased incrementality in compiles. This makes our standard build of googletest exactly like upstream's recommended build and the sanitizer's build. It also simplifies the steps of importing a new version should we ever want one. llvm-svn: 194801

Use -Wl,defs when linking. ELF linkers by default allow shared libraries to contain undefined references and it is up to the dynamic linker to look for them. On COFF and MachO, that is not the case. This creates a situation where a .so might build on an ELF system, but the build of the corresponding .dylib or .dll will fail. This patch changes the cmake build to use -Wl,-z,defs when linking and updates the dependencies so that -DBUILD_SHARED_LIBS=ON build still works. llvm-svn: 226611

Reverting "CMake: Don't include tools, unittets, or examples as available targets unless LLVM_INCLUDE_X is ON. LLVM_BUILD_X implies LLVM_INCLUDE_X" It breaks the configuration phase when cmake is invoked without parameters, it is too complex for the purpose and introduces an incovenience for the user (as both LLVM_BUILD_X and LLVM_INCLUDE_X must set to OFF for not including X on the build) llvm-svn: 114795

LINK_COMPONENTS
Support # Depends on llvm::raw_ostream
[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
