Build LLVM with -DLLVM_ENABLE_TERMINFO=OFF option, then build CppNameLint with -ltinfo option.

Buil LLVM with -DLLVM_ENABLE_TERMINFO=OFF option

$ cmake -DCMAKE_BUILD_TYPE=Release              \
               -DLLVM_ENABLE_PROJECTS=clang     \
               -DLLVM_ENABLE_RTTI=ON            \
               -DLLVM_ENABLE_TERMINFO=OFF       \
               -G "Unix Makefiles"              \
               ../llvm                          \
               > logfile-cmake.log 2>&1

Build CppNameLint project with -ltinfo option

set(CMAKE_CXX_FLAGS "-frtti -lz -ltinfo")
