Subject: [CMake][compiler-rt] Enable statically linking unwinder and c++abi
X-Git-Tag: llvmorg-10-init~13192
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e2c021d8b78cbc4e3288484db7f87d191a20c84d;p=platform%2Fupstream%2Fllvm.git

[CMake][compiler-rt] Enable statically linking unwinder and c++abi

Rather than guessing whether to use static or shared version of
unwinder and c++abi when using linking against the in-tree versions,
provide a CMake option to control this.
