During an exp-run for llvm 15 (see bug 265425), it turned out that
devel/cvise failed to build if devel/llvm15 is also installed:
/wrkdirs/usr/ports/devel/cvise/work/cvise-2.4.0/clang_delta/ExpressionDetector.cpp:62:16: error: 'InclusionDirective' marked 'override' but does not override any member functions
virtual void InclusionDirective(SourceLocation HashLoc,
^
/wrkdirs/usr/ports/devel/cvise/work/cvise-2.4.0/clang_delta/ExpressionDetector.cpp:62:16: warning: '(anonymous namespace)::IncludesPPCallbacks::InclusionDirective' hides overloaded virtual function [-Woverloaded-virtual]
/usr/local/llvm15/include/clang/Lex/PPCallbacks.h:127:16: note: hidden overloaded virtual function 'clang::PPCallbacks::InclusionDirective' declared here: type mismatch at 6th parameter ('Optional<clang::FileEntryRef>' vs 'const clang::FileEntry *')
virtual void InclusionDirective(SourceLocation HashLoc,

1 warning and 1 error generated.
This is because during the configure phase, it picks up
ClangConfig.cmake from the llvm13 package, but LLVMConfig.cmake from the
llvm15 package:
-- Found LLVM 15.0.6
-- Using LLVMConfig.cmake in /usr/local/llvm15/lib/cmake/llvm
-- Using ClangConfig.cmake in /usr/local/llvm13/lib/cmake/clang
-- Found PythonInterp: /usr/local/bin/python3 (found suitable version "3.9.15", minimum required is "3.6")
Add a -DLLVM_DIR flag to CMAKE_ARGS to point to the correct directory
for LLVMConfig.cmake.
