Here's how the problem occured.
My cmakelist.txt
set(CMAKE_CXX_STANDARD 20)
#dpcpp
set(CMAKE_C_COMPILER icx)
set(CMAKE_CXX_COMPILER icx)
find_package(IntelSYCL REQUIRED)
add_executable(sycl_framework_test
sycl_framework_test.cpp
)
add_sycl_to_target(TARGET sycl_framework_test SOURCES sycl_framework_test.cpp)
target_include_directories(sycl_framework_test PRIVATE
./
${SYCL_INCLUDE_DIR}
)
target_link_libraries(sycl_framework_test PRIVATE
${SYCL_LIBRARY}
)
When I cmake it, error is following
[CMake] -- SYCL_INCLUDE_DIR: E:/DevFramework/Intel/oneAPI/compiler/2025.2/include
1> [CMake] -- SYCL_LIBRARY=E:/DevFramework/Intel/oneAPI/compiler/2025.2/lib/sycl8.lib
1> [CMake] SYCL feature test compile failed!
1> [CMake] compile output is:

After I checked my dpc++ files, the problem was locked on a file
Intel\oneAPI\compiler\2025.2\lib\cmake\IntelSYCL\IntelSYCLConfig.cmake
in line 388
SYCL_FEATURE_TEST_EXTRACT(${test_output})
to fix the problem
only need to change this ${test_output} to "${test_output}"
whole cmake instruction is
SYCL_FEATURE_TEST_EXTRACT("${test_output}")
SYCL Compiler version: 20250200
