Subject: cmake: Support exports correctly with LLVM_DISTRIBUTION_COMPONENTS
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=bddcf4b2eba87eb9a5513fc978f885895dd17591;p=clang

cmake: Support exports correctly with LLVM_DISTRIBUTION_COMPONENTS

We need to apply the same export logic in clang as in llvm for
LLVM_DISTRIBUTION_COMPONENTS, or the clang exports will be invalid
when we use this config.

This makes using distribution components without setting
LLVM_TOOLCHAIN_ONLY=On work correctly.
