vs2019装opencv3.4.2cmake报错
作者：互联网
在尝试用cmake编译opencv3.4.2版本的时候，报错如下，
CMake Warning at cmake/OpenCVDetectCXXCompiler.cmake:147 (message): OpenCV does not recognize MSVC_VERSION "1923". Cannot set OpenCV_RUNTIME Call Stack (most recent call first): CMakeLists.txt:153 (include)
错误排查流程：
-
排查出报错的位置。在 opencv-3.4.2\cmake\OpenCVDetectCXXCompiler.cmake 文件的147行。
-
尝试描述该问题，即弄清楚问题是什么——“OpenCV does not recognize MSVC_VERSION “1923”. Cannot set OpenCV_RUNTIME Call Stack (most recent call first)”我的理解是对应的_MSC_VER 1923找不到对应的vc不能设置OpenCV_RUNTIME
-
搜索该问题，一击必中。
解决方法：
if(DEFINED OpenCV_ARCH AND DEFINED OpenCV_RUNTIME)
# custom overridden values
elseif(MSVC)
if(CMAKE_CL_64)
set(OpenCV_ARCH x64)
elseif((CMAKE_GENERATOR MATCHES "ARM") OR ("${arch_hint}" STREQUAL "ARM") OR (CMAKE_VS_EFFECTIVE_PLATFORMS MATCHES "ARM|arm"))
# see Modules/CmakeGenericSystem.cmake
set(OpenCV_ARCH ARM)
else()
set(OpenCV_ARCH x86)
endif()
if(MSVC_VERSION EQUAL 1400)
set(OpenCV_RUNTIME vc8)
elseif(MSVC_VERSION EQUAL 1500)
set(OpenCV_RUNTIME vc9)
elseif(MSVC_VERSION EQUAL 1600)
set(OpenCV_RUNTIME vc10)
elseif(MSVC_VERSION EQUAL 1700)
set(OpenCV_RUNTIME vc11)
elseif(MSVC_VERSION EQUAL 1800)
set(OpenCV_RUNTIME vc12)
elseif(MSVC_VERSION EQUAL 1900)
set(OpenCV_RUNTIME vc14)
//插入注释下面两段话，这里的MSVC_VERSION即表中的_MSC_VER，当1923时，是vc16，使其能识别vs2019的VC++,具体_MSC_VER值见附表
elseif(MSVC_VERSION EQUAL 1910)
set(OpenCV_RUNTIME vc15)
elseif(MSVC_VERSION EQUAL 1923)
set(OpenCV_RUNTIME vc16)
elseif(MSVC_VERSION MATCHES "^193[0-9]$")
set(OpenCV_RUNTIME vc17)
else()
message(WARNING "OpenCV does not recognize MSVC_VERSION \"${MSVC_VERSION}\". Cannot set OpenCV_RUNTIME")
endif()
elseif(MINGW)
set(OpenCV_RUNTIME mingw)
if(MINGW64)
set(OpenCV_ARCH x64)
else()
set(OpenCV_ARCH x86)
endif()
endif()
