[cfe-users] How to use clang-tidy plugin.

[Benjamin Kramer via cfe-users]

Using ASTMatchers in a plugin should work as long as clang doesn't use
them. The problems arise when both the plugin and clang define the
same symbols. But with the current cmake build it's not possible to
just link ASTMatchers, it will drag all dependencies of ASTMatchers
along and cause linker errors.
