This new cmake module allows to generate cmake package files. This may ease the
porting for cmake projects that are exporting cmake package informations for other
depending projects. The module uses as much as possible the templates provided by
the cmake installation (and so cmake needs to be installed).
A custom_target, if install is set to true, will always be built by
default even if build_by_default is explicitly set to false.
Ensure that this does not happen if it's set explicitly. To keep
backward compatibility, if build_by_default is not set explicitly and
install is true, set build_by_default to true.
Fixes#4107
* Fixed spelling
* Merged the Buildoptions and Projectinfo interpreter
* Moved detect_compilers to Environment
* Added removed test case
* Split detect_compilers and moved even more code into Environment
* Moved set_default_options to coredata
* Small code simplification in mintro.run
* Move cmd_line_options back to `environment`
We don't actually wish to persist something this unstructured, so we
shouldn't make it a field on `coredata`. It would also be data
denormalization since the information we already store in coredata
depends on the CLI args.
The returned not-found object can be from any type because we were
returning the first of the failed attempts. It also can happen that we
don't have any dependency object in which case we should just return
NotFoundDependency() object as well instead of raising an exception.
That exception was happening before, but dependency_impl() was
calling find_external_dependency() in a try block so it was hidden.
When req_version is None (e.g. pcap-config case) it gets printed in the
logs.
Take this opportunity to reformat the message to look more like
ExternalProgram messages.
Not need to catch exceptions in dependency_fallback(), it's already
handled in do_subproject(). This ensure subproject errors are handled
the same way when doing dependency() fallback and when doing
subproject().
