Hans Wennborg 71de49afa4 Merging r352374: ... ------------------------------------------------------------------------ r352374 | mgorny | 2019-01-28 16:16:03 +0100 (Mon, 28 Jan 2019) | 18 lines [cmake] Fix get_llvm_lit_path() to respect LLVM_EXTERNAL_LIT always Refactor the get_llvm_lit_path() logic to respect LLVM_EXTERNAL_LIT, and require the fallback to be defined explicitly as LLVM_DEFAULT_EXTERNAL_LIT. This fixes building libcxx standalone after r346888. The old logic was using LLVM_EXTERNAL_LIT both as user-defined cache variable and an optional pre-definition of default value from caller (e.g. libcxx). It included a hack to make this work by assigning the value back and forth but it was fragile and stopped working in libcxx. The new logic is simpler and more transparent. Default value is provided in a separate variable, and used only when user-specified variable is empty (i.e. not overriden).
