CMP0100ΒΆ
Let AUTOMOC and AUTOUIC process
header files that end with a .hh extension.
Since version 3.17, CMake processes header files that end with a
.hh extension in AUTOMOC and AUTOUIC.
In earlier CMake versions, these header files were ignored by
AUTOMOC and AUTOUIC.
This policy affects how header files that end with a .hh extension
get treated in AUTOMOC and AUTOUIC.
The OLD behavior for this policy is to ignore .hh header files
in AUTOMOC and AUTOUIC.
The NEW behavior for this policy is to process .hh header files
in AUTOMOC and AUTOUIC just like other header files.
Note
To silence the CMP0100 warning source files can be excluded from
AUTOMOC and AUTOUIC processing by setting the
source file properties SKIP_AUTOMOC, SKIP_AUTOUIC or
SKIP_AUTOGEN.
# Source skip example:
set_property(SOURCE /path/to/file1.hh PROPERTY SKIP_AUTOMOC ON)
set_property(SOURCE /path/to/file2.hh PROPERTY SKIP_AUTOUIC ON)
set_property(SOURCE /path/to/file3.hh PROPERTY SKIP_AUTOGEN ON)
This policy was introduced in CMake version 3.17.0. CMake version
3.18.6 warns when the policy is not set and uses OLD behavior.
Use the cmake_policy() command to set it to OLD or NEW
explicitly.
Note
The OLD behavior of a policy is
deprecated by definition
and may be removed in a future version of CMake.
