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.

Do you have any hint for this? Thanks, best regards.
That include is for SSE intrisics, obviously won't exist on MIPS.
Cheers,
Sylvain
