• 解决链接：
• https://github.com/strasdat/Sophus/issues/214
• https://www.cnblogs.com/ramlife/p/13740968.html
• 就是在cmakelist那加一句set(CMAKE_CXX_FLAGS "-Wno-error=deprecated-declarations -Wno-deprecated-declarations ")就行了
• 我改的：

cmake_minimum_required(VERSION 3.4)
project(Sophus VERSION 1.0.0)

include(CMakePackageConfigHelpers)

# Release by default
# Turn on Debug with "-DCMAKE_BUILD_TYPE=Debug"
if(NOT CMAKE_BUILD_TYPE)
  set(CMAKE_BUILD_TYPE Release)
endif()

set(CMAKE_CXX_STANDARD 11)

# Set compiler specific settings (FixMe: Should not cmake do this for us automatically?)
IF("${CMAKE_CXX_COMPILER_ID}" STREQUAL "Clang")
   SET(CMAKE_CXX_FLAGS_DEBUG  "-O0 -g")
   SET(CMAKE_CXX_FLAGS_RELEASE "-O3")
   SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wall -Werror -Wextra -Wno-deprecated-register -Wno-deprecated-register -Qunused-arguments -fcolor-diagnostics")
ELSEIF("${CMAKE_CXX_COMPILER_ID}" STREQUAL "GNU")
   SET(CMAKE_CXX_FLAGS_DEBUG  "-O0 -g")
   SET(CMAKE_CXX_FLAGS_RELEASE "-O3")
   SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wall -Werror -Wextra -std=c++11 -Wno-deprecated-declarations -ftemplate-backtrace-limit=0")
   SET(CMAKE_CXX_FLAGS_COVERAGE "${CMAKE_CXX_FLAGS_DEBUG} --coverage -fno-inline -fno-inline-small-functions -fno-default-inline")
   SET(CMAKE_EXE_LINKER_FLAGS_COVERAGE "${CMAKE_EXE_LINKER_FLAGS_DEBUG} --coverage")
   SET(CMAKE_SHARED_LINKER_FLAGS_COVERAGE "${CMAKE_SHARED_LINKER_FLAGS_DEBUG} --coverage")
ELSEIF(CMAKE_CXX_COMPILER_ID MATCHES "^MSVC$")
   ADD_DEFINITIONS("-D _USE_MATH_DEFINES /bigobj /wd4305 /wd4244 /MP")
ENDIF()

set(CMAKE_CXX_FLAGS "-Wno-error=deprecated-declarations -Wno-deprecated-declarations ")
