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.
The `gtest-config' script provides access to the necessary compile and linking
flags to connect with Google C++ Testing 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 gtest. 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:
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
g++ $(gtest-config --cppflags --cxxflags) -o foo.o -c foo.cpp
g++ $(gtest-config --ldflags --libs) -o foo foo.o
# When using a built but not installed Google Test:
g++ $(../../my_gtest_build/scripts/gtest-config ...) ...
# When using an installed Google Test, but with installation overrides:
export GTEST_PREFIX="/opt"
g++ $(gtest-config --libdir="/opt/lib64" ...) ...

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 INC installation
--version the version of the Google Test installation
Version Queries:
--min-version=VERSION return 0 if the version is at least VERSION
