Google Test comes with a CMake build script (
|

[CMakeLists.txt](https://github.com/google/googletest/blob/master/CMakeLists.txt)) that can be used on a wide range of platforms ("C" stands for
|
||||
cross-platform.). If you don't have CMake installed already, you can

download it for free from <http://www.cmake.org/>.

|

If you want to use gtest in a project which already uses CMake, then a
|
||||
more robust and flexible approach is to build gtest as part of that
|
||||
project directly. This is done by making the GoogleTest source code
|
||||
available to the main build and adding it using CMake's
|
||||
`add_subdirectory()` command. This has the significant advantage that
|
||||
the same compiler and linker settings are used between gtest and the
|
||||
rest of your project, so issues associated with using incompatible
|
||||
libraries (eg debug/release), etc. are avoided. This is particularly
|
||||
useful on Windows. Making GoogleTest's source code available to the

main build can be done a few different ways:
|
||||
|
||||
* Download the GoogleTest source code manually and place it at a
|
||||
known location. This is the least flexible approach and can make
|
||||
it more difficult to use with continuous integration systems, etc.
|
||||
* Embed the GoogleTest source code as a direct copy in the main
|
||||
project's source tree. This is often the simplest approach, but is
|
||||
also the hardest to keep up to date. Some organizations may not
|
||||
permit this method.
|
||||
* Add GoogleTest as a git submodule or equivalent. This may not
|
||||
always be possible or appropriate. Git submodules, for example,
|
||||
have their own set of advantages and drawbacks.
|
||||
* Use CMake to download GoogleTest as part of the build's configure

step. This is just a little more complex, but doesn't have the

limitations of the other methods.

The last of the above methods is implemented with a small piece

of CMake code in a separate file (e.g. `CMakeLists.txt.in`) which
|
||||
is copied to the build area and then invoked as a sub-build

_during the CMake stage_. That directory is then pulled into the

By default, new Visual Studio projects link the C runtimes dynamically
|
||||
but Google Test links them statically.

||||
This will generate an error that looks something like the following:
|
||||
gtest.lib(gtest-all.obj) : error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MTd_StaticDebug' doesn't match value 'MDd_DynamicDebug' in main.obj

Before settling on CMake, we have been providing hand-maintained build

continue to provide them for convenience, they are not actively

are ready to build Google Test the same way you build any Visual
|
||||
Studio project. Files that have names ending with -md use DLL
|
||||
versions of Microsoft runtime libraries (the /MD or the /MDd compiler
|
||||
option). Files without that suffix use static versions of the runtime
|
||||
libraries (the /MT or the /MTd option). Please note that one must use
|
||||
the same option to compile both gtest and the test code. If you use
|
||||
Visual Studio 2005 or above, we recommend the -md version as /MD is
|
||||
the default for new projects in these versions of Visual Studio.

Google Test can be used in diverse environments. The default

these macros are named like `GTEST_XYZ` and you define them to either 1

When Google Test uses pthread, you may need to add flags to your compiler and/or
|
||||
linker to select the pthread library, or you'll get link errors. If you use the
|
||||
CMake script or the deprecated Autotools script, this is taken care of for you.
|
||||
If you use your own build script, you'll need to read your compiler and linker's
|
||||
manual to figure out what flags to add.

### Avoiding Macro Name Clashes
|

|

In C++, macros don't obey namespaces. Therefore two libraries that
|
||||
both define a macro of the same name will clash if you `#include` both
|
||||
definitions. In case a Google Test macro clashes with another
|
||||
library, you can force Google Test to rename its macro to avoid the
|
||||
conflict.
