Visual c++ CMake仅在带有g++；选项

当我从

CMakeLists.txt

中删除

-g

和

-O3

选项时，我的MSVC失败，并出现许多错误，如：

libcpmt.lib(xwcscoll.obj) : error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MT_StaticRelease' doesn't match value 'MD_DynamicRelease' in ExamplesTest.obj

我不理解这个奇怪的错误，因为它清楚地写着：

忽略未知选项'-g'

和

忽略未知选项'-O3'

CMakeLists.txt，可以正常工作

CMakeLists.txt不起作用

你能解释一下CMA在工作案例中做了哪些额外的步骤吗

编辑： 我已经测试、重建和清理了好几次，我几乎可以肯定错误来自那里。

这是因为

set（CMAKE\u CXX\u FLAGS\u DEBUG“-g”）

和

set（CMAKE\u CXX\u FLAGS\u RELEASE“-O3”）重载了现有的设置。
当我使用MSVC编译时，我只是为
CMAKE\u CXX\u FLAGS\u RELEASE
和
CMAKE\u CXX\u FLAGS\u RELEASE
设置了一个值
