Subject: Revert "[CMake] Don't enable BUILD_WITH_INSTALL_RPATH when using custom build rpath"
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=913c430403b52b9336ed93fabbac363a3e18536a;p=android-x86%2Fexternal-llvm-project.git

Revert "[CMake] Don't enable BUILD_WITH_INSTALL_RPATH when using custom build rpath"

This reverts commit 0ebc1fb29f278db0665423f15c53e6ee9601dddb.

The behaviour should have been the same as before unless specifying CMAKE_BUILD_RPATH,
which was previously broken.
However, this seems to have broken builds for some people that don't specify it.
Reverting until I can investigate.
