Add CMake script to setup and build ANGLE · 4e39779aAntonio Maiorano authored
This change adds CMake targets that setup and build ANGLE by invoking gclient and gn. The 'angle-setup' target should run only once (if the .gclient file does not exist), and the 'angle' target will build if any source file under angle/src is modfied. The 'angle' target builds libEGL and libGLESv2 into ${CMAKE_BINARY_DIR}/bin-angle. Furthermore, if building PowerVR examples are enabled (SWIFTSHADER_BUILD_PVR), the PVR output folder, ${CMAKE_BINARY_DIR}/bin, gets copied to ${CMAKE_BINARY_DIR}/bin-angle first. Finally, a script named 'export-swangle-env.bat/sh' also gets copied to ${CMAKE_BINARY_DIR}/bin-angle, which sets environment variables so that the PowerVR examples will run on "SWANGLE" (that is, on ANGLE on SwiftShaderVK). Example on Linux: cd SwiftShader/build cmake -DSWIFTSHADER_BUILD_PVR=1 -DSWIFTSHADER_BUILD_ANGLE=1 .. cmake --build . --target angle source bin-angle/export-swangle-env.sh ./bin-angle/OpenGLESBumpmap On Windows, run bin-angle\export-swangle-env.bat, and execute the examples from the bin-angle directory.
