This converts the CMake license to a pure 3-clause OSI-approved BSD
License. We drop the previous license clause requiring modified
versions to be plainly marked. We also update the CMake copyright to
cover the full development time range.
A name with an ambiguous extension may only match an unambiguous name
that is extended by one of the fixed set of extensions tried when
finding the source file on disk. This rule makes matching of source
files with ambiguous extensions much less aggressive but still
sufficient.
For historical reasons we still support naming of source files without
their extension. Sources without known extensions are located on disk
by iterating through a fixed set of possible extensions. We now want
users to always specify the extension, so the fixed set will not be
expanded and is preserved for compatibility with older projects.
This change adds recognition of extensions of all enabled languages to
avoid checking the disk for files whose extensions are unambiguous but
not in the original fixed set.
CMake-SourceFile2-bp and CMake-SourceFile2-b-mp1 to trunk. This
commit is surrounded by tags CMake-SourceFile2-b-mp1-pre and
CMake-SourceFile2-b-mp1-post on the trunk.
The changes re-implement cmSourceFile and the use of it to allow
instances to be created much earlier. The use of cmSourceFileLocation
allows locating a source file referenced by a user to be much simpler
and more robust. The two SetName methods are no longer needed so some
duplicate code has been removed. The strange "SourceName" stuff is
gone. Code that created cmSourceFile instances on the stack and then
sent them to cmMakefile::AddSource has been simplified and converted
to getting cmSourceFile instances from cmMakefile. The CPluginAPI has
preserved the old API through a compatibility interface.
Source lists are gone. Targets now get real instances of cmSourceFile
right away instead of storing a list of strings until the final pass.
TraceVSDependencies has been re-written to avoid the use of
SourceName. It is now called TraceDependencies since it is not just
for VS. It is now implemented with a helper object which makes the
code simpler.
