From c3a7cc34fb0fb842d0453e5330a60148f804298b Mon Sep 17 00:00:00 2001 From: Max Krummenacher Date: Mon, 10 Jan 2022 21:52:02 +0000 Subject: [PATCH] cmake: sdlchecks.cmake: pass cflags to the appropriate cmake variable If egl.pc sets at least two macros as the i.MX Vivante driver does, e.g.: | Cflags: -I${includedir} -DLINUX -DWL_EGL_PLATFORM then we get the following error during configuration: | -- Performing Test HAVE_OPENGL_EGL | CMake Error: Parse error in command line argument: WL_EGL_PLATFORM | Should be: VAR:type=value If one changes to add a value to the macro, e.g. | Cflags: -I${includedir} -DLINUX=1 -DWL_EGL_PLATFORM=1 then cmake does not error out but the macro is not passed to the C compiler. CMAKE_REQUIRED_FLAGS is the wrong variable to pass the CFLAGS in, CMAKE_REQUIRED_DEFINITIONS should be used.
