Recently there has been some discussion about how we deal with optional dependencies in LLDB. The approach in LLVM is to make things work out of the box. If the dependency isn't there, we move on silently. That's not true for LLDB. Unless you explicitly disable the dependency with LLDB_ENABLE_*, you'll get a configuration-time error. The historical reason for this is that LLDB's dependencies have a much broader impact, think about Python for example which is required to run the test suite. The current approach can be frustrating from a user experience perspective. Sometimes you just want to ensure LLDB builds with a change in clang. This patch changes the optional dependencies (with the exception of Python) to a new scheme. The LLDB_ENABLE_* now takes three values: On, Off or Auto, with the latter being the default. On and Off behave the same as today, forcing the dependency to be enabled or disabled. If the dependency is set to On but is not found, it results in a configuration time warning. For Auto we detect if the dependency is there and either enable or disable it depending on whether it's found. Differential revision: https://reviews.llvm.org/D71306 PS: The reason Python isn't included yet is because it's so pervasive that I plan on doing that in a separate patch.
