CMP0070ΒΆ
Define file(GENERATE) behavior for relative paths.
CMake 3.10 and newer define that relative paths given to INPUT and
OUTPUT arguments of file(GENERATE) are interpreted relative to the
current source and binary directories, respectively. CMake 3.9 and lower did
not define any behavior for relative paths but did not diagnose them either
and accidentally treated them relative to the process working directory.
Policy CMP0070 provides compatibility with projects that used the old
undefined behavior.
This policy affects behavior of relative paths given to file(GENERATE).
The OLD behavior for this policy is to treat the paths relative to the
working directory of CMake. The NEW behavior for this policy is to
interpret relative paths with respect to the current source or binary
directory of the caller.
This policy was introduced in CMake version 3.10. CMake version
3.15.3 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.
