Error on relative include with generator expression.
Diagnostics in CMake 2.8.12 and lower silently ignored an entry in the
INTERFACE_INCLUDE_DIRECTORIES
of a target if it contained a generator
expression at any position.
The path entries in that target property should not be relative. High-level API should ensure that by adding either a source directory or a install directory prefix, as appropriate.
As an additional diagnostic, the INTERFACE_INCLUDE_DIRECTORIES
generated
on an IMPORTED
target for the install location should not contain
paths in the source directory or the build directory.
The OLD
behavior for this policy is to ignore relative path entries if they
contain a generator expression. The NEW
behavior for this policy is to report
an error if a generator expression appears in another location and the path is
relative.
This policy was introduced in CMake version 3.0. CMake version
3.27.9 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.
