On dashmacmini2 the test showed output like this:
-- Found PythonInterp: /usr/bin/python (found version "Unknown option: --
usage: /usr/bin/python [option] ... [-c cmd | file | -] [arg] ...
Try `python -h' for more information.")
On my machine where python outputs "Python 2.7" this worked, but
PYTHON_VERSION_MAJOR, PYTHON_VERSION_MINOR, and PYTHON_VERSION_PATCH were all
set to "2.7".
Add some checks that the version output has the expected form before using it.
This allows the developer to tell FindPythonInterp which Python version should
be searched for. This allows the right version to be chosen for a project
without user assistance if there are specific requirements. This is especially
useful as it is common to have major versions 2 and 3 installed in parallel,
which are partly incompatible.

Otherwise the compiler may optimize out the reference to the symbol as the
previous version was not really using this. This leads to symbols that are
only in a header but not in the given libraries to be reported as present.
This came up on the first try to fix bug 11333 as "gcc -O3" would optimize
out the reference to pthread_create() so the correct library the symbol is in
was not detected.
The new test code was suggested by Brad King.
When we have no MPI compiler wrapper and search explicitly for the MPI
C++ library append it correctly to the list of libraries instead of
using a space.

Since commit 183b9509 (Follow all dependencies of shared library private
dependencies, 2011-12-14) we honor LINK_INTERFACE_LIBRARIES when
following dependent shared libraries. The link interface properties may
form a cycle if set incorrectly by a project. Furthermore, the property
LINK_DEPENDENT_LIBRARIES may form a cycle if set incorrectly by hand
(though CMake should never generate one). In either case, do not follow
the cycle forever when following the dependent shared library closure.
We only need to add dependency edges to the constraint graph once.
Add "LinkInterfaceLoop" test to cover this case.
Some tests only need to run CMake to configure and generate a build
tree, but not actually perform the build. Add a new "Tests/CMakeOnly"
directory dedicated for this purpose. Add a helper script to drive each
test by creating a fresh build tree and running CMake on it. Add macro
"add_CMakeOnly_test" to help create tests using the script.
Use the approach originally used in commit f91b3c1d (Add options to
build with system utility libraries, 2006-10-19) for all other
third-party libraries. Create a "cm_bzlib.h" header wrapper that
robustly includes the header from the bzip2 library chosen for the CMake
build (either builtin or system version). Include the header wrapper
anywhere we need the API provided by <bzlib.h>.
This wasn't necessary for TAR-like (TGZ, TBZ2, etc...) archive
because for those the size was 0. Either there is an error in
upstream libarchive concerning the size or we should not rely
on size of the entry for adding content.
First this fixes the bug that e.g. version "1.0.0" was shown as "1..". When
pkg-config was used to find OpenSSL the header file was parsed for the version
number even if pkg-config returned it already. Finally we also include the
patch level (i.e. the letter after the version number) in OPENSSL_VERSION.
When GIT_EXECUTABLE points at ".../Git/cmd/git.cmd" in an msysGit
installation we previously failed to detect the version number in a
subtle case. The "git.cmd" assumes 'chcp' is in PATH. It is typically
available at "C:\Windows\System32\chcp.com". On 64-bit Windows the File
System Redirector maps this location to "C:\Windows\SysWOW64\chcp.com"
for 32-bit processes. However, some Windows installations fail to
provide chcp.com at this path. Whenever git.cmd runs in a 32-bit
command shell, as it does under a 32-bit CMake binary, it reports
'chcp' is not recognized as an internal or external command,
operable program or batch file.
on stderr. Capture stderr separately so it does not affect parsing
of the version number.
See also msysGit issue 358:
http://code.google.com/p/msysgit/issues/detail?id=358
Note that FindGit prefers "git.cmd" over "git.exe" because it sets up
the proper HOME environment variable necessary for Git ssh connections
to work the same as they do from the Git bash prompt.
Decode decimal digits from _SGI_COMPILER_VERSION or _COMPILER_VERSION to
compute version number components. See documentation at:
http://predef.sourceforge.net/precomp.html
The MSVC, HP, XL, SunPro, Watcom, Borland, and Intel compilers specify
their version number in components encoded in a single integer value.
Document the components that we use to compute version numbers.
