cmake を使用して opencv 用の sfm モジュールをコンパイルできません。

次のログは、cmake が glog と gflags の両方を見つけたが、コンパイルが失敗したことを示しています。

前の出力を引き起こす"opencv_contrib\modules\sfm\CmakeLists.txt"のコード スニペットを次に示します。

if((gflags_FOUND OR GFLAGS_FOUND OR GFLAGS_INCLUDE_DIRS) AND (glog_FOUND OR GLOG_FOUND OR GLOG_INCLUDE_DIRS))

  file(WRITE "${_fname}" "#include <glog/logging.h>\n#include <gflags/gflags.h>\n int main() { (void)(0); return 0; }\n")

  // This is reason of the fail
  try_compile(SFM_DEPS_OK "${CMAKE_BINARY_DIR}" "${_fname}"
      CMAKE_FLAGS "-DINCLUDE_DIRECTORIES:STRING=${GLOG_INCLUDE_DIRS};${GFLAGS_INCLUDE_DIRS}"
      LINK_LIBRARIES ${GLOG_LIBRARIES} ${GFLAGS_LIBRARIES}
      OUTPUT_VARIABLE OUTPUT
  )
  file(REMOVE "${_fname}")
  message(STATUS "Checking SFM deps... ${SFM_DEPS_OK}")
else()
  set(SFM_DEPS_OK FALSE)
endif()

if(NOT HAVE_EIGEN OR NOT SFM_DEPS_OK)
  set(DISABLE_MSG "Module opencv_sfm disabled because the following dependencies are not found:")
  if(NOT HAVE_EIGEN)
    set(DISABLE_MSG "${DISABLE_MSG} Eigen")
  endif()
  if(NOT SFM_DEPS_OK)
    set(DISABLE_MSG "${DISABLE_MSG} Glog/Gflags")
  endif()
  message(STATUS ${DISABLE_MSG})
  ocv_module_disable(sfm)
endif()

cmake の gflags と glog パスに問題があると思います。より多くのバリエーションを試しました。現在の設定は次のとおりです。それらのほとんどは、 Ceres Solver のドキュメントに基づいて設定されています。

構成：

  • OpenCV 4.5.0
  • OpenCV-contrib 4.5.0
  • グログ 0.4.0
  • gflags 2.2.2
  • セレス ソルバー 2.0.0
  • 固有値 3.3.9
  • CMake 3.9.12
  • ウィンドウズ10
