CXX_SCAN_FOR_MODULESΒΆ
New in version 3.26.
CXX_SCAN_FOR_MODULES is a boolean specifying whether CMake will scan the
source for C++ module dependencies. See also the
CXX_SCAN_FOR_MODULES for target-wide settings.
When this property is set ON, CMake will scan the source at build time and
add module dependency information to the compile line as necessary. When this
property is set OFF, CMake will not scan the source at build time. When
this property is unset, the CXX_SCAN_FOR_MODULES property is
consulted.
Note that scanning is only performed if C++20 or higher is enabled for the
target and the source uses the CXX language. Scanning for modules in
sources belonging to file sets of type CXX_MODULES and
CXX_MODULES_HEADER_UNITS is always performed.
Note
This setting is meaningful only when experimental support for C++ modules
has been enabled by the CMAKE_EXPERIMENTAL_CXX_MODULE_CMAKE_API gate.
