Don't add executable dependencies to link ones ...

At some point executable dependencies will need dedicated "pathDependency"
support. For now those better be ignored - no one is going to link against
an executable.

remove unnecessary check for directories starting with dot

Modify copyFiles to allow recursive copying of directories with contents, if directory name is specified in file list (or matched by wildcard)

fix MartinNowak's finding - wildcard copyDirs should be applied to directories only

Implement copyDirs parameter, similar to copyFiles - should recursively copy directory content to destination

Mention what to do with linkDependencies when building.

Add some more documentation in the Generator class.

Remove PackageManager argument from createProjectGenerator(). ...

The argument is also removed from all Generator sub classes.

Add basic documentation for the Generator class and improve method protection.

In copyFiles, check if entry is glob before treating it as such

Added glob support to copyFiles

Fix trying to copy copyFiles where source==destination.

Added singleFile support

Add a --temp-build switch to force building in the TEMP folder. Fixes #294.

Only add platform flags for targets that generate an actual binary. Fixes #346.

Removed trailing whitespace

Add the --build-mode switch to control how the compiler and linker are invoked.

Process variables for pre-/postGenerateCommands.

Fix copying "copyFiles".

Run executables _after_ generation has finished. ...

In particular, the generated application is run after the copyFiles have been placed. This is a fix for a regression that was introduced after the last release version.

Collect build targets after running preGenerateCommands. Fixes #144. ...

This enables used generated source files without listing each of them manually. Now a single "sourcePaths" entry is sufficient.

Rename Project.mainPackage to rootPackage. ...

Root package better describes the package's role of the root of the dependency hierarchy.

correct imports

Merge branch 'dustmite'

Silence debugging log message

Don't downward inherit Have_* versions and only partially string import paths. ...

This change allows library builds to be reused for multiple dependees in most situations. String import paths are now only downwards inherited for packages that already have string import paths defined.

Only insert packages belonging to the same target into TargetInfo.packages.

Add support for execution result callbacks in the build generator.

Fix handling of targetType none packages and automatically treat packages with no source files as targetType none.
