QNX has the phtread stuff in the standard library. The best way would
IMHO be to check if a program that uses pthread_* can be successfully
linked without specifying any linker option before trying out the
different flags.
This removes some useless checking. The results of these things are never
properly checked so they should not count as testcases. At the end they only
needlessly clutter the output.
Change to consider a library embedded if it is found in a subdirectory relative to the
using executable/library. Previous commit considered them local.
This case is encountered when @rpath is used with framework libraries, which are inside a directory tree.
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.
