If Impala was built with --build_shared_libs, some thirdparty libraries were still statically linked; this could cause runtime errors if the libraries were also linked into a .so. This patch fixes that issue (for gflags, glog and protobuf at least) by ensuring that build_shared_libs is respected for those libraries. * Standardize thirdparty library handling w/CMake by adding IMPALA_ADD_THIRDPARTY_LIB. This creates a symbolic name for each library, allowing us to switch the underlying library files (e.g. change from static to dynamic linking) without having to individually change the link clauses for each target. * Remove most cases of add_library() from cmake_modules/* - that is all handled by IMPALA_ADD_THIRDPARTY_LIB. * Add shared library detection for a couple of thirdparty dependencies (many only detect static libraries), just to prove the concept. * All thirdparty libraries now print a standard set of messages. For example: -- ----------> Adding thirdparty library protoc. <---------- -- Header files: /data/henry/src/cloudera/impala-toolchain/protobuf-2.6.1/include -- Added shared library dependency protoc: /data/henry/src/cloudera/impala-toolchain/protobuf-2.6.1/lib/libprotoc.so -- ----------> Adding thirdparty library libev. <---------- -- Header files: /data/henry/src/cloudera/impala-toolchain/libev-4.20/include -- Added shared library dependency libev: /data/henry/src/cloudera/impala-toolchain/libev-4.20/lib/libev.so * Some libraries don't quite fit this pattern (LLVM and Boost) - leave them as is for now. * Remove FindOpenSSL.cmake - the toolchain one is more modern.
