# compile_spirv.cmake
|

# Compila shaders GLSL a SPIR-V y genera headers C++ embebibles.
|
||||
# Multiplataforma: Windows, macOS, Linux (no requiere bash, xxd ni /tmp/).
|
||||
#
|
||||
# Invocado por CMakeLists.txt con:
|
||||
# cmake -D GLSLC=<path> -D SHADERS_DIR=<path> -D HEADERS_DIR=<path> -P compile_spirv.cmake
|
||||
#
|
||||
# También puede ejecutarse manualmente desde la raíz del proyecto:
|
||||
# cmake -D GLSLC=glslc -D SHADERS_DIR=data/shaders -D HEADERS_DIR=source/core/rendering/sdl3gpu -P tools/shaders/compile_spirv.cmake
