Subject: Stop enabling clang-tools-extra automatically when clang is in LLVM_ENABLE_PROJECTS
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=3e53c14be52f1a5c36952b3a3861202e3f201fc6;p=llvm

Stop enabling clang-tools-extra automatically when clang is in LLVM_ENABLE_PROJECTS

If you want to build clang-tools-extra with monorepo, just add it to
LLVM_ENABLE_PROJECTS like with other projects.

See also "Separating clang-tools-extra from clang in LLVM_ENABLE_PROJECTS"
on cfe-dev.
