Introduction

This is an integration test of Abseil in a Modern CMake C++ Project using ExternalProject module.

We try to integrate abseil-cpp using add_subdirectory(abseil-cpp) or by installing it first (in astaging area) then using find_package(absl).

This project should run on Linux, Mac and Windows.

CMake Dependencies Tree

This CMake project is composed of one executable (FooApp) and one library (Foo) with the following dependencies:

absl:
Foo: absl::strings
FooApp: Foo, absl::strings

Strategy 1: add_subdirectory(abseil-cpp)

To see the integration of abseil-cpp as add_subdirectory() please take a look at the branch add_subdirectory

spoiler: This is not working (as intended)

Strategy 2: find_package(absl)

To see the integration of abseil-cpp using find_package() (and local staging install) please take a look at the branch install

spoiler: This is the way to go
