Cannot determine location of C++ headers for runtime.

Describe the bug

During the configuration of cling cmake doesn't find the paths to include directories

-- Cling version (from VERSION file): 0.9
CMake Warning at tools/cling/lib/Interpreter/CMakeLists.txt:278 (MESSAGE):
  Cannot determine location of C++ headers for runtime.


-- Cling will look for C++ headers in '' at runtime.
-- And then fallback to: 'c++'

Expected behavior

cmake should be able to find the directories, yet it seems the sed - command fails

To Reproduce

As everyones system is different I share the output of what I think is passed to the sed command to find the #include paths: (it is a german machine with manjaro linux)

Setup

1. Cling version: 0.9
2. Operating system: manjaro linux
3. How you obtained Cling, such as with cpt.py (also mention flags) / you built it yourself: I tried ./cpt.py --check-requirements && ./cpt.py --create-dev-env Debug --with-workdir=./cling-build/ but it failed at the end due to no space left in /tmp.

So I grabbed the buildfile from the arch AUR-archive and copied the cmake command:

~/.../cling-build/builddir >>> cmake \                                         
        -DCMAKE_BUILD_TYPE=Release \
        -DCMAKE_INSTALL_PREFIX="/opt/cling09" \
        -DLLVM_TARGETS_TO_BUILD="host;NVPTX" \
        -DLLVM_BUILD_LLVM_DYLIB=OFF \
        -DLLVM_ENABLE_RTTI=ON \
        -DLLVM_ENABLE_FFI=ON \
        -DLLVM_BUILD_DOCS=OFF \
        -DLLVM_BUILD_TOOLS=OFF \
        -DLLVM_ENABLE_SPHINX=OFF \
        -DLLVM_ENABLE_DOXYGEN=OFF \
        -DFFI_INCLUDE_DIR=$(pkg-config --cflags-only-I libffi | cut -c3-) ../cling-src

Additional context

cling compiles anyway and when I try to use it:

~/.../cling-build/builddir >>> cling                                      [130]
