C++ modules have two variants which are of importance to CMake:
- `CXX_MODULES`: interface modules (those using `export module M;`,
`export module M:part;`, or `module M:internal_part;`)
- `CXX_MODULE_HEADER_UNITS`: importable header units
Creating C++ modules or partitions are *not* supported in any other
source listing. This is because the source files must be installed (so
their scope matters), but not part of usage requirements (what it means
for a module source to be injected into a consumer is not clear at this
moment). Due to the way `FILE_SET` works with scopes, they are a perfect
fit as long as `INTERFACE` is not allowed (which it is not).

Semicolon-separated list of base directories of the target's default
|
|
C++ module set (i.e. the file set with name and type ``CXX_MODULES``). The
|
|
property supports
|
|
:manual:`generator expressions <cmake-generator-expressions(7)>`.
|
|
|
|
This property is normally only set by :command:`target_sources(FILE_SET)`
|
|
rather than being manipulated directly.
|
|
|
|
See :prop_tgt:`CXX_MODULE_DIRS_<NAME>` for the list of base directories in
|
|
other C++ module sets.
