Verifying the config fails if option is disabled but prerequisites exist, that seems flawed? #23083
Description
I have a problem building openCV without support for V4L. I pass the cmake option -DWITH_V4L=OFF but then I get a build error.
I found the error comes from
opencv/cmake/OpenCVUtils.cmake
Line 788 in 9208dcb
But the logic seems flawed in my exes: Why should the build fail if WITH_V4L is OFF just because the prerequisites exist? Its great that the prerequisites exist but that does not imply that I actually want to use them in the build, or does it?
I call cmake with:
cmake /home/Src/opencv -GNinja -DCMAKE_PREFIX_PATH=/data/Debug;/data/Debug/lib/cmake;/data/Extras;/data/Extras/lib/cmake -DCMAKE_MODULE_PATH=/data/Tools/share/bda/cmake -DCMAKE_INSTALL_PREFIX=/data/Debug -DCMAKE_BUILD_TYPE=Debug -DCMAKE_CXX_STANDARD=20 -DCMAKE_CXX_STANDARD_REQUIRED=ON -DCMAKE_CXX_EXTENSIONS=NO -DCMAKE_INSTALL_LIBDIR=lib -DCMAKE_INSTALL_DATADIR=lib -DBUILD_SHARED_LIBS=OFF -DBUILD_WITH_DEBUG_INFO=ON -DENABLE_OMIT_FRAME_POINTER=OFF -DOPENCV_INCLUDE_INSTALL_PATH=include -DOPENCV_CONFIG_INSTALL_PATH=share/opencv -DOPENCV_OTHER_INSTALL_PATH=share/opencv -DENABLE_PIC=ON -DBUILD_LIST=core,imgproc,imgcodecs,ml,video,videoio,features2d,flann,gapi -DOPENCV_ENABLE_NONFREE=OFF -DPROTOBUF_UPDATE_FILES=OFF -DUPDATE_PROTO_FILES=OFF -DWITH_MATLAB=OFF -DOPENCV_FORCE_3RDPARTY_BUILD=OFF -DBUILD_ZLIB=OFF -DBUILD_TIFF=OFF -DBUILD_OPENJPEG=OFF -DBUILD_JASPER=OFF -DBUILD_JPEG=OFF -DBUILD_PNG=OFF -DBUILD_OPENEXR=OFF -DBUILD_WEBP=OFF -DBUILD_TBB=OFF -DBUILD_IPP_IW=OFF -DBUILD_ITT=OFF -DWITH_CUDA=OFF -DWITH_1394=OFF -DWITH_AVFOUNDATION=OFF -DWITH_CAP_IOS=OFF -DWITH_CAROTENE=OFF -DWITH_CPUFEATURES=OFF -DWITH_VTK=OFF -DWITH_EIGEN=ON -DWITH_FFMPEG=OFF -DWITH_GSTREAMER=OFF -DWITH_GTK=OFF -DWITH_GTK_2_X=OFF -DWITH_WAYLAND=OFF -DWITH_IPP=ON -DOPENCV_IPP_GAUSSIAN_BLUR=ON -DWITH_HALIDE=OFF -DWITH_VULKAN=OFF -DWITH_INF_ENGINE=OFF -DWITH_NGRAPH=OFF -DWITH_JASPER=OFF -DWITH_OPENJPEG=OFF -DWITH_JPEG=OFF -DWITH_WEBP=OFF -DWITH_OPENEXR=OFF -DWITH_OPENGL=OFF -DWITH_OPENVX=OFF -DWITH_OPENNI=OFF -DWITH_OPENNI2=OFF -DWITH_PNG=ON -DWITH_SPNG=OFF -DWITH_GDCM=OFF -DWITH_PVAPI=OFF -DWITH_ARAVIS=OFF -DWITH_QT=OFF -DWITH_WIN32UI=OFF -DWITH_TBB=ON -DWITH_HPX=OFF -DWITH_OPENMP=OFF -DWITH_PTHREADS_PF=OFF -DWITH_TIFF=ON -DWITH_V4L=OFF -DWITH_DSHOW=OFF -DWITH_MSMF=OFF -DWITH_MSMF_DXVA=OFF -DWITH_XIMEA=OFF -DWITH_XINE=OFF -DWITH_CLP=OFF -DWITH_OPENCL=OFF -DWITH_OPENCL_SVM=OFF -DWITH_OPENCLAMDFFT=OFF -DWITH_OPENCLAMDBLAS=OFF -DWITH_DIRECTX=OFF -DWITH_OPENCL_D3D11_NV=OFF -DWITH_LIBREALSENSE=OFF -DWITH_VA=OFF -DWITH_VA_INTEL=OFF -DWITH_MFX=OFF -DWITH_GDAL=OFF -DWITH_GPHOTO2=OFF -DMKLROOT=/data/Extras/mkl -DWITH_MKL=ON -DMKL_WITH_TBB=ON -DWITH_LAPACK=OFF -DWITH_ITT=OFF -DWITH_PROTOBUF=OFF -DWITH_IMGCODEC_HDR=OFF -DWITH_IMGCODEC_SUNRASTER=OFF -DWITH_IMGCODEC_PXM=OFF -DWITH_IMGCODEC_PFM=OFF -DWITH_QUIRC=OFF -DWITH_ANDROID_MEDIANDK=OFF -DWITH_ADE=OFF -DBUILD_opencv_apps=OFF -DBUILD_opencv_js=OFF -DBUILD_ANDROID_PROJECTS=OFF -DBUILD_ANDROID_EXAMPLES=OFF -DBUILD_DOCS=OFF -DBUILD_EXAMPLES=ON -DBUILD_PACKAGE=OFF -DBUILD_PERF_TESTS=OFF -DBUILD_TESTS=ON -DBUILD_WITH_STATIC_CRT=OFF -DBUILD_WITH_DYNAMIC_IPP=OFF -DBUILD_FAT_JAVA_LIB=OFF -DBUILD_ANDROID_SERVICE=OFF -DBUILD_CUDA_STUBS=OFF -DBUILD_JAVA=OFF -DBUILD_OBJC=OFF -DBUILD_KOTLIN_EXTENSIONS=OFF -DINSTALL_CREATE_DISTRIB=OFF -DINSTALL_C_EXAMPLES=OFF -DINSTALL_PYTHON_EXAMPLES=OFF -DINSTALL_ANDROID_EXAMPLES=OFF -DINSTALL_TO_MANGLED_PATHS=OFF -DINSTALL_TESTS=OFF -DENABLE_PRECOMPILED_HEADERS=OFF -DENABLE_SOLUTION_FOLDERS=OFF -DENABLE_PROFILING=OFF -DENABLE_COVERAGE=OFF -DOPENCV_ENABLE_MEMORY_SANITIZER=OFF -DENABLE_POWERPC=OFF -DENABLE_FAST_MATH=ON -DENABLE_NEON=OFF -DENABLE_VFPV3=OFF -DENABLE_NOISY_WARNINGS=OFF -DOPENCV_WARNINGS_ARE_ERRORS=OFF -DANDROID_EXAMPLES_WITH_LIBS=OFF -DENABLE_IMPL_COLLECTION=OFF -DENABLE_INSTRUMENTATION=OFF -DENABLE_GNU_STL_DEBUG=OFF -DENABLE_BUILD_HARDENING=OFF -DENABLE_LTO=OFF -DENABLE_THIN_LTO=OFF -DGENERATE_ABI_DESCRIPTOR=OFF -DOPENCV_GENERATE_PKGCONFIG=OFF -DCV_ENABLE_INTRINSICS=ON -DCV_DISABLE_OPTIMIZATION=OFF -DCV_TRACE=OFF -DOPENCV_GENERATE_SETUPVARS=OFF -DENABLE_CONFIG_VERIFICATION=ON -DOPENCV_ENABLE_MEMALIGN=ON -DENABLE_PYLINT=OFF -DENABLE_FLAKE8=OFF -DCPU_BASELINE=AVX2 -DPACKAGE_DISTRIBUTION=OFF
