| 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 |

| # 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. |
