Subject: [CMake] Get rid of generating obj.*-tblgen if CMake >= 3.9 for Ninja generator.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=5b6663a260689c3f1756f409c8a3f7edf015b313;p=llvm

[CMake] Get rid of generating obj.*-tblgen if CMake >= 3.9 for Ninja generator.

CMake-3.9 doesn't let compilation units depend on their dependent libraries.
