sdrangelove build issues on mipsel

[F4EXB]

Hello Sylvain,

this include is made only if USE_SIMD is set and the key is in the CMakeLists.txt at top level:

IF(CMAKE_SYSTEM_PROCESSOR MATCHES "x86_64|AMD64|x86")
 SET(USE_SIMD "SSE2" CACHE STRING "Use SIMD instructions")
ENDIF()

then...

if(USE_SIMD MATCHES SSE2)
	if(CMAKE_COMPILER_IS_GNUCXX OR CMAKE_COMPILER_IS_CLANGXX)
		set( CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} -msse2" )
		set( CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG} -msse2" )
		add_definitions(-DUSE_SIMD)
	elseif(MSVC)
		set( CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG} /arch:SSE2" )
		set( CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} /Oi /GL /Ot /Ox /arch:SSE2" )
		set( CMAKE_EXE_LINKER_FLAGS_RELEASE "${CMAKE_EXE_LINKER_FLAGS_RELEASE} /LTCG" )
		add_definitions (/D "_CRT_SECURE_NO_WARNINGS")
		add_definitions(-DUSE_SIMD)
	endif()
endif()

If you try to cross compile from a x86_64 host it will believe it can use SIMD. Or maybe your MIPS system shows as a x86_64 with cmake.
If nothing else works you can comment the lines:

IF(CMAKE_SYSTEM_PROCESSOR MATCHES "x86_64|AMD64|x86")
 SET(USE_SIMD "SSE2" CACHE STRING "Use SIMD instructions")
ENDIF()

Best regards,
Edouard.
