The \`gtest-config' script provides access to the necessary compile and linking
flags to connect with Google C++ Testing framework. The installation queries
may only be issued one at a time, and may not be issued with any other types of
queries. The version queries and compiler flag queries may be combined as
desired but not mixed. Different version queries are always combined with "and"
logical semantics, and only the last of any particular query is used and 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:
gtest-config --min-version=1.0 || echo "Insufficient Google Test version."
gcc \$(gtest-config --cppflags --cxxflags) -o foo.o -c foo.cpp
gcc \$(gtest-config --ldflags --libs) -o foo foo.o
Help:
--usage brief usage information
--help display this help message
Installation Queries:
--prefix installation prefix
--exec-prefix executable installation prefix
--libdir library installation directory
--includedir header file installation directory
--version the version of the INC 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" 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.
