Use recommended case for variable names. i.e. matching name of the
module as passed to `find_package`.
For backwards compatibility, the upper case versions of both input and
output variables are used and defined when appropriate. Skip this for
the _FOUND variable because FPHSA already does it. Skip this for the
_VERSION variable because that was recently added and never available
with the old name in a release of CMake.
Also detect the library version number. Provide results as variables
and as an imported target, LTTng::UST.

Check found libraries version to match user required version.
Protobuf compiler executable version is checked to be aligned with found
libraries, raising a warning message otherwise.
Since commit v3.3.0-rc1~397^2 (Check*CompilerFlag: Refactor method used
to pass flags, 2015-02-24) these check modules pass the flags to the
compiler front-end during linking as well as during compilation. This
breaks checks for flags like '-x c++' that are meant only for the
compilation step. Revert the change and add a test covering a
compiler-only flag.
The FindKDE4 module (incorrectly) modifies CMAKE_MODULE_PATH on the
caller's behalf. This causes KDE4-installed find modules to be used by
the test instead of those in CMake. Teach the test to restore the
CMAKE_MODULE_PATH to its original value after each find_package call.
This ensures that the next find_package actually tests our module.
Previously if headers required to check if a struct has a member can be
compiled with C++ compiler only, the check would fail because the C
compiler fails. As a consequence, the result variable would be set to
false, even if the struct has that particular member.
Teach CHECK_STRUCT_HAS_MEMBER to accept a new optional argument LANGUAGE
that allows one to explicitly set the compiler to use. The new
signature is therefore:
CHECK_STRUCT_HAS_MEMBER (<struct> <member> <header> <variable>
[LANGUAGE <language>])
If one of the libraries (_DEBUG or _RELEASE) is not set, the value is
set to the value of the other one. FindQt4, from which the macro is
extracted, sets the values to XXX_LIBRARY_{DEBUG,RELEASE}-NOTFOUND
instead. In both cases the XXX_LIBRARY is correct, but using NOTFOUND
makes it easier to understand which one is missing.
Update Tests/CMakeOnly/SelectLibraryConfigurations with the new logic.

For things where we may have 2 major versions of the same software
installed in parallel (think of Qt and Python) make sure our version
selection gets this right.
When more than one value is given to the NAMES option this command by
default will consider one name at a time and search every directory for
it. Add a NAMES_PER_DIR option to tell this command to consider one
directory at a time and search for all names in it.
In Tests/CMakeOnly/find_library/CMakeLists.txt generalize the
test_find_library macro and move the lib64 substitution logic to a new
test_find_library_subst macro.

Ancient versions of CMake required else(), endif(), and similar block
termination commands to have arguments matching the command starting the
block. This is no longer the preferred style.
Run the following shell code:
for c in else endif endforeach endfunction endmacro endwhile; do
echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
egrep -z -v 'Tests/CMakeTests/While-Endwhile-' |
xargs -0 sed -i -f convert.sed &&
rm convert.sed
When a search path contains multiple "lib/" instances we previously
converted all or none. This fails for cases where only some of the
multiple instances must be converted. Teach AddArchitecturePaths to
generate all combinations that exist. Uncomment these cases in the
CMakeOnly.find_library test now that they work.
Add a "CMakeOnly.find_library" test covering various cases involving
lib->lib64 (non-)conversion. Comment out cases involving mixed path
components "lib" and "lib64", such as lib/A/lib64 and lib64/A/lib, as
these are known to be broken currently.
Our only expectation of version number variables should be that
they begin with a decimal digit for VERSION_LESS, VERSION_EQUAL
and VERSION_GREATER comparison purposes. If people put extra
blah blah after a version number like "1.2.3 (this is some super
special extra information about our funky proprietary build of
the official 1.2.3 release)" then we should be ok with that.
So: now we have the following expectations for version number
variable content for the purposes of the AllFindModules test:
- it should start with a decimal digit (match "^[0-9]")
- it should not be empty
- it should not be VERSION_EQUAL 0
- it should not be NOT VERSION_GREATER 0
For all current build machines the modules FindPkgConfig, FindFreetype, and
FindLibXslt return a version number. Enforce this to early catch when this
is not always the case.
