 The following libraries are required to build libopenshot.

-### CMake Flags (Optional)
-There are many different build flags that can be passed to cmake to adjust how libopenshot is compiled. Some of these flags might be required when compiling on certain OSes, just depending on how your build environment is setup.

-To add a build flag, follow this general syntax:

-```sh
-$ cmake -DMAGICKCORE_HDRI_ENABLE=1 -DENABLE_TESTS=1 ..

-Following are some of the flags you might need to set when generating your build system.

-##### Optional behavior:
-* `-DENABLE_TESTS=0` (default: `ON`)
-* `-DENABLE_COVERAGE=1` (default: `OFF`)
-* `-DENABLE_DOCS=0` (default: `ON` if doxygen found)

-##### Compiler configuration:
-* `-DCMAKE_BUILD_TYPE=Debug` (default: `Release`)
-* `-DCMAKE_CXX_FLAGS="-Wall -Wextra"` (default: auto for build type)
-* `-DCMAKE_CXX_COMPILER=/path/to/g++`
-* `-DCMAKE_C_COMPILER=/path/to/gcc` (used by CMake for OS probes)

-##### Dependency configuration:
-* `-DCMAKE_PREFIX_PATH=/extra/path/to/search/for/libraries/`

 ## Obtaining Source Code
 
 The first step in installing libopenshot is to obtain the most recent source code. The source code is available on [GitHub](https://github.com/OpenShot/libopenshot). Use the following command to obtain the latest libopenshot source code.
