+### CMake configure options
 
+##### Core library options:
+
+* `-DVKVG_USE_GLUTESS=true`: Use embedded glu tesselator to fill polygones in NON-ZERO mode. If false, a simple ear clipping algorithm is used.
+* `-DVKVG_VKVG=true`: Enable experimental svg renderer. If false, use nanoSVG.
+* `-DVKVG_RECORDING=true`: Enable experimental draw commands recording infrastructure.
+* `-DVKVG_BUILD_DOCS=true`: Build documentation enabled if doxygen is found.
+
+##### Text rendering libraries:
+
+Those libraries are enabled by default, but disabled if not found.
+* `-DVKVG_USE_FONTCONFIG=true`: enable FontConfig to resolve font's names.
+* `-DVKVG_USE_FREETYPE=true`: enable FreeType to render glyphs, if false glyphs are rendered with stb_freetype.
+* `-DVKVG_USE_HARFBUZZ=true`: enable harfbuzz for text shaping.
+
+##### Tests options:
+
+* `-DVKVG_BUILD_TESTS=true`: build all tests in the tests forlder.
+* `-DVKVG_TEST_DIRECT_DRAW=true`: enable drawing directly on the swapchain images.
+
+##### Debugging options:
+
+If vkvg is compiled with `CMAKE_BUILD_TYPE=Debug`, several additional options are made available to help debugging:
+* `-DENABLE_VALIDATION=true`: enable vulkan validation layer.
+* `-DENABLE_DBG_UTILS=true`: enable various vulkan debug utils extensions features.
+* `-DENABLE_RENDERDOC=true`: enable renderdoc layer.
+* `-DENABLE_WIRED_FILL=true`: enable rendering in wired mode, current mode is controled with the global variable `vkvg_wired_debug`.
+* `-DENABLE_PROFILING=true`: add -pg to the compile options.
+* `-DVKVG_DBG_STATS=true`: store various context statistics fetchable with `vkvg_device_get_stats()`
+
+```bash
+cmake --build .
