Set compiler option to default In CMake

Question

How can I set "Basic Runtime Checks" to "Default" in my CMake file?

With following line in CMake, I can set it to RTCs in Release mode, but what I really need is set it to Default.

set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} /RTCs")

I found the solution.

Use macro to delete the current compiler option.

macro(RemoveDebugCXXFlag flag)
    string(REPLACE "${flag}" "" CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG}")
endmacro()

macro(RemoveReleaseCXXFlag flag)
    string(REPLACE "${flag}" "" CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE}")
endmacro()

message(${CMAKE_CXX_FLAGS_DEBUG}) # Print Debug Flags Before Change
RemoveDebugCXXFlag("/RTC1")

message(${CMAKE_CXX_FLAGS_DEBUG}) # Print Debug Flags After Change

message(${CMAKE_CXX_FLAGS_RELEASE}) # Print Release Flags Before Change
RemoveReleaseCXXFlag("/RTC1")
message(${CMAKE_CXX_FLAGS_RELEASE}) # Print Release Flags After Change
