Glog - CMake Support

Glog comes with a CMake build script (CMakeLists.txt) that can be used on a wide range of platforms.
If you don't have CMake installed already, you can download it for free from http://www.cmake.org/.

CMake works by generating native makefiles or build projects that can be used in the compiler environment of your choice.
You can either build Glog with CMake as a standalone project or it can be incorporated into an existing CMake build for another project.

Building Glog with CMake

When building Glog as a standalone project, on Unix-like systems with GNU Make as build tool, the typical workflow is:

1. Get the source code and change to it. e.g. cloning with git:

git clone git@github.com:google/glog.git
cd glog

2. Run CMake to configure the build tree.

cmake -H. -Bbuild -G "Unix Makefiles"

note: To get the list of available generators (e.g. Visual Studio), use -G ""

3. Afterwards, generated files can be used to compile the project.

cmake --build build

4. Test the build software (optional).

cmake --build build --target test

5. Install the built files (optional).

cmake --build build --target install

Consuming Glog in a CMake Project

If you have Glog installed in your system, you can use the CMake command find_package() to include it in your CMake Project.

cmake_minimum_required(VERSION 3.0.2)
project(myproj VERSION 1.0)

find_package(glog 0.4.0 REQUIRED)

add_executable(myapp main.cpp)
target_link_libraries(myapp glog::glog)

Compile definitions and options will be added automatically to your target as needed.

Incorporating Glog into a CMake Project

You can also use the CMake command add_subdirectory() to include Glog directly from a subdirectory of your project.
The glog::glog target is in this case an ALIAS library target for the glog library target.

cmake_minimum_required(VERSION 3.0.2)
project(myproj VERSION 1.0)

add_subdirectory(glog)

add_executable(myapp main.cpp)
target_link_libraries(myapp glog::glog)

Again, compile definitions and options will be added automatically to your target as needed.
