Introduce policy CMP0047 to control resetting the id for
compatibility.
De-duplicate content in the QNX platform file by including the GNU
one. QNX is a form of GNU platform.
Do not clear CMAKE_SHARED_LIBRARY_${lang}_FLAGS variables. They
are populated again later by the Compiler/GNU.cmake file anyway.
Modify the CMAKE_CXX_COMPILE_OBJECT variable only when the QCC
compiler id is in use, and the language is CXX. Use the QNX
recommended flag for QCC instead of the gcc compatible -x flag.
Populate new module files to handle system includes and depfiles
when using the QCC compiler.
Remove code which unsets the system include and depfiles related
variables. When a GNU driver is used instead of the QCC one, the
appropriate flags will be used. These variables were previously
cleared for lowest-common-denominator compatibility with both
drivers.
Mark unknown revisions as such and fail instead of reporting revision 0.
Otherwise CTest reports massive file updates between revisions when the
server timeouts while trying to fetch the current revision number.
Define a new 'CMAKE_CONFIGURE_DEPENDS' directory property that projects
can use to specify input files to the CMake configuration process.
Extend the RunCMake.Configure test to verify that the build system
re-runs CMake when this input changes.
Extend the RunCMake.Configure with a case to verify that the CMake
configuration process does not immediately re-run the first time that
the generated build system is invoked.
The logic added by commit ffc0b5e4 (Overwrite the symlink if it already
exists, 2007-02-15) does not recognize and remove existing broken links
before replacing them. Improve the logic to remove any existing
destination file or link (but not directory). On failure, report an
error message explaining why the existing path could not be removed or
the new one could not be created.
Add a RunCMake.CommandLine test to cover 'cmake -E' cases. Start with
test cases covering 'cmake -E create_symlink' behavior on UNIX platforms.
Add a 'run_cmake_command' function that can be used by tests to run a
given command-line and check the results rather than always running a
CMake configuration process. This can be used in the future to test
'cmake -E' for example.
In commit 2412d9bc (Use 'uname -m' for processor on Cygwin, 2010-09-21)
it was pointed out that POSIX requires 'uname -m' but not 'uname -p':
http://www.opengroup.org/onlinepubs/9699919799/utilities/uname.html
On OS X x86_64, 'uname -p' returns i386 while 'uname -m' returns x86_64.
Since the latter is the POSIX-compliant option trust its value.
However, on OS X ppc, 'uname -m' returns 'Power Macintosh' so add a
special-case to convert that to 'powerpc'.
Workaround binutils bug by only marking unique section starting by
".text._".
This adds the HPPA workaround improved in commit b22a0f15 (bootstrap:
improve ld flag for Linux/HPPA builds, 2014-01-14) not only to the
bootstrap, but also to the normal build.
...otherwise the generator failed in embedded projects via
externalproject(), since there CMAKE_KATE_MAKE_ARGUMENT is not set.
Using GetSafeDefinition() is good enough to protect against
NULL-pointers.
