IMPORTED_CXX_MODULES_COMPILE_OPTIONS — CMake 3.29.3 Documentation

# IMPORTED_CXX_MODULES_COMPILE_OPTIONS

New in version 3.28.

List of options to pass to the compiler for this `IMPORTED` target's C++ modules.

## Option De-duplication

The final set of options used for a target is constructed by accumulating options from the current target and the usage requirements of its dependencies. The set of options is de-duplicated to avoid repetition.

New in version 3.12: While beneficial for individual options, the de-duplication step can break up option groups. For example, `-option A -option B` becomes `-option A B`. One may specify a group of options using shell-like quoting along with a `SHELL:` prefix. The `SHELL:` prefix is dropped, and the rest of the option string is parsed using the `separate_arguments()` `UNIX_COMMAND` mode. For example, `"SHELL:-option A" "SHELL:-option B"` becomes `-option A -option B`.
