Custom command path normalization added in commit v3.1.0-rc1~471^2
(add_custom_command: Normalize OUTPUT and DEPENDS paths, 2014-05-28)
broke use of OBJECT_DEPENDS to bring in custom commands because the
latter paths were not normalized too. Normalize them and add a test
case.

For complex*, CustomCommand and OutDir tests, non-ascii paths
are avoided in test code by using relative paths, and setting
the working when running the test. This also avoids the
need to internationalize the test code.
For RunCMake.GeneratorExpression, use a UTF-8 encoding in
file(STRINGS) to retrieve the compiled absolute path correctly.
- Option was recently added but never released.
- Custom commands no longer depend on build.make so we do
not need the option.
- Rule hashes now take care of rebuilding when rules change
so the dependency is not needed.
- Allows make rules to be created with no dependencies.
- Such rules will not re-run even if the commands themselves change.
- Useful to create rules that run only if the output is missing.
