Summary:
cmake fails with an error when attempting to evaluate $<TARGET_FILE:tgt>
where `tgt` is defined via an `add_custom_target` and thus the `TYPE`
is `UTILITY`. Requesting a TARGET_FILE only works on an `EXECUTABLE`
or one of a few differetnt types of `X_LIBRARY` (e.g. added via
`add_library` or `add_executable`). The logic as implemented in cmake
is below:
enum TargetType
{
EXECUTABLE,
STATIC_LIBRARY,
SHARED_LIBRARY,
MODULE_LIBRARY,
OBJECT_LIBRARY,
UTILITY,
GLOBAL_TARGET,
INTERFACE_LIBRARY,
UNKNOWN_LIBRARY
};
if (target->GetType() >= cmStateEnums::OBJECT_LIBRARY &&
target->GetType() != cmStateEnums::UNKNOWN_LIBRARY) {
::reportError(context, content->GetOriginalExpression(),
"Target \"" + name +
"\" is not an executable or library.");
return nullptr;
}
This has always been the case back to at least 3.12 (furthest I
checked) but this is causing a new failure in cmake 3.17 while
evaluating ExternalProjectAdd.
