The `gmock-config' script provides access to the necessary compile and linking
flags to connect with Google C++ Mocking Framework, both in a build prior to
installation, and on the system proper after installation. The installation
overrides may be issued in combination with any other queries, but will only
affect installation queries if called on a built but not installed gmock. The
installation queries may not be issued with any other types of queries, and
only one installation query may be made at a time. The version queries and
compiler flag queries may be combined as desired but not mixed. Different
version queries are always combined with logical "and" semantics, and only the
last of any particular query is used while all previous ones ignored. All
versions must be specified as a sequence of numbers separated by periods.
Compiler flag queries output the union of the sets of flags when combined.
Examples:
gmock-config --min-version=1.0 || echo "Insufficient Google Mock version."
g++ $(gmock-config --cppflags --cxxflags) -o foo.o -c foo.cpp
g++ $(gmock-config --ldflags --libs) -o foo foo.o
# When using a built but not installed Google Mock:
g++ $(../../my_gmock_build/scripts/gmock-config ...) ...
# When using an installed Google Mock, but with installation overrides:
export GMOCK_PREFIX="/opt"
g++ $(gmock-config --libdir="/opt/lib64" ...) ...
Help:
--usage brief usage information
--help display this help message
Installation Overrides:
--prefix=<dir> overrides the installation prefix
--exec-prefix=<dir> overrides the executable installation prefix
--libdir=<dir> overrides the library installation prefix
--includedir=<dir> overrides the header file installation prefix
Installation Queries:
--prefix installation prefix
--exec-prefix executable installation prefix
--libdir library installation directory
--includedir header file installation directory
--version the version of the Google Mock installation
Version Queries:
--min-version=VERSION return 0 if the version is at least VERSION
--exact-version=VERSION return 0 if the version is exactly VERSION
--max-version=VERSION return 0 if the version is at most VERSION
Compilation Flag Queries:
--cppflags compile flags specific to the C-like preprocessors
--cxxflags compile flags appropriate for C++ programs
--ldflags linker flags
--libs libraries for linking

# This function bounds our version with a min and a max. It uses some clever
# POSIX-compliant variable expansion to portably do all the work in the shell
# and avoid any dependency on a particular "sed" or "awk" implementation.
# Notable is that it will only ever compare the first 3 components of versions.
# Further components will be cleanly stripped off. All versions must be
# unadorned, so "v1.0" will *not* work. The minimum version must be in $1, and
# the max in $2. TODO(chandlerc@google.com): If this ever breaks, we should
# investigate expanding this via autom4te from AS_VERSION_COMPARE rather than
# continuing to maintain our own shell version.
