## Abseil CMake build instructions
### Recommended usage : incorporate Abseil into an CMake project
We recommended to build and use abseil in the same way than googletest
( https://github.com/google/googletest/blob/master/googletest/README.md )
* Download abseil and copy it in a sub-directory in your project.
* Or add abseil as a git-submodule in your project
You can then use the cmake `add_subdirectory()` command to include
abseil directly and use the abseil targets in your project.
Abseil requires CCTZ and the googletest framework. Consequently,
the targets `gtest`, `gtest_main`, `gmock` and `cctz` need
to be declared in your project before including abseil with `add_subdirectory`.
You can find instructions on how to get and build these projects at these
URL :
* cctz https://github.com/google/cctz
* googletest https://github.com/google/googletest
Here is a short CMakeLists.txt example of a possible project file
using abseil
project(my_project)
add_subdirectory(googletest)
add_subdirectory(cctz)
add_subdirectory(abseil-cpp)
add_executable(my_exe source.cpp)
target_link_libraries(my_exe base synchronization strings)
