CMP0188ΒΆ
Added in version 4.1.
The FindGCCXML module is removed.
CMake 4.0 and below provide the FindGCCXML module, but the GCC-XML
tool has long been superseded by CastXML. CMake 4.1 and above prefer to not
provide the FindGCCXML module. This policy provides compatibility
for projects that have not been ported away from it.
The OLD behavior of this policy is for find_package(GCCXML) to load
the deprecated module. The NEW behavior is for find_package(GCCXML)
to fail as if the module does not exist.
This policy was introduced in CMake version 4.1.
It may be set by cmake_policy() or cmake_minimum_required().
If it is not set, CMake warns, and uses OLD behavior.
Note
The OLD behavior of a policy is
deprecated by definition
and may be removed in a future version of CMake.
