No type named MakeGL in GrDirectContext (or GrContext)

During the compilation of the application I realized that GrDirectContext and GrContext hasn't type named MakeGL. The skia build flags were these:

skia_use_system_libjpeg_turbo = false
skia_use_system_libwebp = false
skia_use_system_expat = false
skia_use_system_libpng = false
skia_use_system_freetype2 = false
ndk="/home/allan/Android/Sdk/ndk/21.3.6528147"
target_os="android" 
target_cpu="arm"
is_debug=false
is_component_build=true
extra_cflags=["-O3"]
skia_use_angle = false
skia_use_icu = false
skia_use_lua = false
skia_use_opencl = false
skia_use_piex = false
skia_use_zlib = false
skia_enable_tools = false
skia_enable_pdf = false
skia_use_gl = true
skia_enable_skottie = false

This was the error log:

../../../../../../../../sources/main.cpp:203:55: error: no type named 'MakeGL' in 'GrDirectContext'

Let's see the skia code snippet:

#ifdef SK_GL
    /**
     * Creates a GrDirectContext for a backend context. If no GrGLInterface is provided then the
     * result of GrGLMakeNativeInterface() is used if it succeeds.
     */
    static sk_sp<GrDirectContext> MakeGL(sk_sp<const GrGLInterface>, const GrContextOptions&);
    static sk_sp<GrDirectContext> MakeGL(sk_sp<const GrGLInterface>);
    static sk_sp<GrDirectContext> MakeGL(const GrContextOptions&);
    static sk_sp<GrDirectContext> MakeGL();
#endif

Apparently the SK_GL flag is not being set correctly. My workaround was just adding -DCMAKE_CXX_FLAGS="-DSK_GL" to my build script.
