-# Glog - CMake Support
-
-Glog comes with a CMake build script ([CMakeLists.txt](../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:
-```bash
-git clone git@github.com:google/glog.git
-cd glog
-```
-
-2. Run CMake to configure the build tree.
-```bash
-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.
-```bash
-cmake --build build
-```
-
-4. Test the build software (optional).
-```bash
-cmake --build build --target test
-```
-
-5. Install the built files (optional).
-```bash
-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
-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
-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.
