CMake重写本地编译器标志
我正在尝试使用Visual Studio 14构建使用CMake的ac项目，但是我无法覆盖由CMake设置的导致项目无法构建的编译器标志。 我在我的CMakeLists.txt文件中使用这种方法
set(flags /nologo /c /EHsc /GS- /MTd /Od /TC /Zi /Zp2 /D _USING_V110_SDK71_)
set(CMAKE_C_FLAGS ${flags})
set(rc_flags /l0x809)
set(CMAKE_RC_FLAGS ${rc_flags})
set(linker_flags /NOLOGO /SUBSYSTEM:console /MACHINE:I386 /DLL)
set(CMAKE_LINKER_FLAGS ${linker_flags})
任何帮助将不胜感激！
编辑：主CMakeLists.txt的完整示例在这里
cmake_minimum_required(VERSION 3.4)
project(cuism C)
set(WINDOWS_SDK_INCLUDES "C:/Program Files (x86)/Microsoft SDKs/Windows/v7.1A/Include/")
set(WINDOWS_SDK_LIBRARIES "C:/Program Files (x86)/Microsoft SDKs/Windows/v7.1A/Lib")

${includeDir}
${resourceDir}
)

set(CMAKE_INCLUDE_PATH ${WINDOWS_SDK_INCLUDES})
set(flags "/nologo /c /EHsc /GS- /MTd /Od /TC /Zi /Zp2 /D _USING_V110_SDK71_" )
set(CMAKE_C_FLAGS ${flags})

set(CMAKE_RC_FLAGS ${rc_flags})
set(linker_flags /NOLOGO /SUBSYSTEM:console /DLL)
set(CMAKE_LINKER_FLAGS ${linker_flags})
message(c flags are ${CMAKE_C_FLAGS})
message(rc flags are ${CMAKE_RC_FLAGS})

message(linker EXE flags are ${CMAKE_EXE_LINKER_FLAGS})
set(EXECUTABLE_OUTPUT_PATH ${CMAKE_BINARY_DIR}/bin)
set(LIBRARY_OUTPUT_PATH ${CMAKE_BINARY_DIR}/bin)
set(RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/bin)
ADD_SUBDIRECTORY(cuimbct)
ADD_SUBDIRECTORY(cuimb)
ADD_SUBDIRECTORY(cuidll)
每个sudbdirectory都有一个类似于这个的CMakeLists.txt
set(src cuimb.c "${includeDir}port.c" cuimben.c cuimb.rc)
add_library(cuimb SHARED ${src})
target_link_libraries(cuimb ${WSOCK} ${ODBC} ${ODBCCP})
由于错误代码LNK2019，错误处于链接阶段
我已经给你的代码尝试了一下，并进行了一些小的修改，可以成功地应用这些编译器/链接器选项。 它包括我和@Tsyvarev所提出的更改（引用和使用CMAKE_SHARED_LINKER_FLAGS ），并且已经删除了对Windows SDK 7.1的静态引用。 这可以使用-T工具集选项进行设置：
> cmake -H"." -B"buildWin7" -T"v140_xp" -G"Visual Studio 14 2015"

建议
为了保持您的CMake脚本代码清洁，您应该将所有编译器/链接器选项移至工具链文件。 我添加了一些我通常在那里定义的选项。 另外，我将它减少为单个配置MyDebug （只是Debug将附加其他调试选项），因为您的选项似乎不是用于Release 。
