It seems that some Apple LLVM wrappers emit multiple messages containing the
string "version", which we previously used to find the version number. For
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr ... Apple LLVM version 9.0.0 (clang-900.0.37) Target: x86_64-apple-darwin16.7.0 Thread model: posix InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/... Found CUDA installation: /usr/local/cuda, version 8.0
We now take care to only look at the first occurrence of this string.
New sed command due to @merijn.
