Something like this would sort of do it.
```
target_compile_options(your_target
PRIVATE
$<$<COMPILE_LANGUAGE:CXX>:$<$<CONFIG:Debug>:${CMAKE_CXX_FLAGS_RELEASE}>>
$<$<COMPILE_LANGUAGE:C>:$<$<CONFIG:Debug>:${CMAKE_C_FLAGS_RELEASE}>>
```
The problem you have though is that `your_target` in debug mode will
already debug build flags (e.g. `-O0 g`). So you may get conflicting
compiler options.
Another way of doing this is to build your target as an external
project where you set the build mode of the external project to be
release.
