1.20 +The `gtest-config' script provides access to the necessary compile and linking
1.21 +flags to connect with Google C++ Testing Framework, both in a build prior to
1.22 +installation, and on the system proper after installation. The installation
1.23 +overrides may be issued in combination with any other queries, but will only
1.24 +affect installation queries if called on a built but not installed gtest. The
1.25 +installation queries may not be issued with any other types of queries, and
1.26 +only one installation query may be made at a time. The version queries and
1.27 +compiler flag queries may be combined as desired but not mixed. Different
1.28 +version queries are always combined with logical "and" semantics, and only the
1.29 +last of any particular query is used while all previous ones ignored. All
1.30 +versions must be specified as a sequence of numbers separated by periods.
1.31 +Compiler flag queries output the union of the sets of flags when combined.
1.32 +
1.33 + Examples:
1.34 + gtest-config --min-version=1.0 || echo "Insufficient Google Test version."
1.35 +
1.36 + g++ $(gtest-config --cppflags --cxxflags) -o foo.o -c foo.cpp
1.37 + g++ $(gtest-config --ldflags --libs) -o foo foo.o
1.38 +
1.39 + # When using a built but not installed Google Test:
1.40 + g++ $(../../my_gtest_build/scripts/gtest-config ...) ...
1.41 +
1.42 + # When using an installed Google Test, but with installation overrides:
1.43 + export GTEST_PREFIX="/opt"
1.44 + g++ $(gtest-config --libdir="/opt/lib64" ...) ...

1.50 + Installation Overrides:
1.51 + --prefix=<dir> overrides the installation prefix
1.52 + --exec-prefix=<dir> overrides the executable installation prefix
1.53 + --libdir=<dir> overrides the library installation prefix
1.54 + --includedir=<dir> overrides the header file installation prefix
1.55 +
1.56 + Installation Queries:
1.57 + --prefix installation prefix
1.58 + --exec-prefix executable installation prefix
1.59 + --libdir library installation directory
1.60 + --includedir header file installation directory
1.61 + --version the version of the Google Test installation
1.62 +
1.63 + Version Queries:
1.64 + --min-version=VERSION return 0 if the version is at least VERSION
1.65 + --exact-version=VERSION return 0 if the version is exactly VERSION
1.66 + --max-version=VERSION return 0 if the version is at most VERSION
1.67 +
1.68 + Compilation Flag Queries:
1.69 + --cppflags compile flags specific to the C-like preprocessors
1.70 + --cxxflags compile flags appropriate for C++ programs
1.71 + --ldflags linker flags
1.72 + --libs libraries for linking
