Makefile

# This Makefile fragment (since dpkg 1.19.0) defines the following variables
# for host tools:
#
# AS: Assembler (since dpkg 1.19.1).
# CPP: C preprocessor.
# CC: C compiler.
# CXX: C++ compiler.
# OBJC: Objective C compiler.
# OBJCXX: Objective C++ compiler.
# F77: Fortran 77 compiler.
# FC: Fortran 9x compiler.
# LD: Linker.
# STRIP: Strip objects (since dpkg 1.19.1).
# OBJCOPY: Copy objects (since dpkg 1.19.1).
# OBJDUMP: Dump objects (since dpkg 1.19.1).
# NM: Names lister (since dpkg 1.19.1).
# AR: Archiver (since dpkg 1.19.1).
# RANLIB: Archive index generator (since dpkg 1.19.1).
# PKG_CONFIG: pkg-config tool.
# QMAKE: Qt build system generator (since dpkg 1.20.0).
#
# All the above variables have a counterpart variable for the build tool,
# as in CC → CC_FOR_BUILD.
#
# The variables are not exported by default. This can be changed by
# defining DPKG_EXPORT_BUILDTOOLS.
#
# Note:
# - Only documented variables are considered public interfaces.
# - Expects to be included from the source tree root directory.
