Bug#994422: blhc: False positive: CPPFLAGS missing (-D_FORTIFY_SOURCE=2): /usr/lib/ccache/c++ -dM -E -c /usr/share/cmake-3.16/Modules/CMakeCXXCompilerABI.cpp

[Eriberto Mota]

Complementing, my local build jail uses  /usr/bin/c++, but Salsa uses
/usr/lib/ccache/c++. Consequently, my current rule in debian/rules is:

@echo 'blhc: ignore-line-regexp: /usr/(bin|lib)/(ccache/)?c\+\+ -dM -E
-c /usr/share/cmake-[0-9.]+/Modules/CMakeCXXCompilerABI.cpp .*'

Regards,
