Subject: [PATCH 01/14] Add \<executable\>/../include/c++/v1 to include path
On macOS, when clang is invoked via a symlink, since the InstalledDir is
where the link is located, the C++ headers are not identified and the
default system headers are used.
This fix adds a second check using the folder where the executable is
located.
