Makes it easy to override it, by priming the cache from a release
build script, for example.
Also: correct mistaken @@ variable references with plain ${}
style references so that future readers do not think that it
must be an input to configure_file...
Remove old search paths that aren't needed.
Keep using PATHS instead of HINTS because a Windows machine may have
a different Qt in its PATH and putting QTDIR and the registry entry
ahead of PATH could cause apps to fail when run.
Add options HG_REPOSITORY and HG_TAG to specify an external project
hosted in a Mercurial repository. Teach ExternalProject to clone the
repository and update from it. Extend the ExternalProject test to try a
Mercurial repository when hg is available.
Previously, it was inconsistent in that some platforms/compilers
had this flag for the RelWithDebInfo configuration and some didn't.
This fixes issue #11366.
...comparison operator in the IF command. In the event of
a tie, we intentionally return "true" so that dependent
build operations are guaranteed to occur until one file
is definitively newer than the other file.
A tie means we're not sure, so return true to be on the
safe side.
SORT, REVERSE, and REMOVE_DUPLICATES can only operate on exactly one argument.
Until now all other arguments were silently ignored. Give an error instead.
This expression evaluates to '1' or '0' to indicate whether the build
configuration for which the expression is evaluated matches tha named
configuration. In combination with the "$<0:...>" and "$<1:...>"
expressions this allows per-configuration content to be generated.
Add generator expressions that combine and use boolean test results:
$<0:...> = empty string (ignores "...")
$<1:...> = content of "..."
$<AND:?[,?]...> = '1' if all '?' are '1', else '0'
$<OR:?[,?]...> = '0' if all '?' are '0', else '1'
$<NOT:?> = '0' if '?' is '1', else '1'
These will be useful to evaluate (future) boolean query expressions and
condition content on the results. Include tests and documentation.
Since commit 571dc748 (Recognize Clang C and C++ compilers, 2010-05-17)
we recognize Clang C and C++ support. Add Compiler/Clang-ASM.cmake to
enable use of Clang for ASM too. Also teach Assembler test to try Clang
as an assembler.

Especially remove "lib64" when the given paths are all Unix ones and "lib" is
also explicitely given. In that case CMake will search "lib64" anyway for
platforms where it is known to make sense.
Instead of directly passing $ENV{SOMEVAR} to a find_* call pass in ENV SOMEVAR.
This will make sure the paths will get correctly handled through different
platforms, especially on Windows.
Also fixes one place where paths with windows delimiters (\) were hardcoded to
use forward slashes.
Since commit 77543bde (Convert CMake-language commands to lower case,
2012-08-13) the CMakeVersion.cmake file contains lower-case 'set'
commands. Teach CMakeVersion.bash to replace the lower-case name
instead of the old upper-case 'SET'.
After conversion of Modules .cmake files to lower case the
FAIL_REGULAR_EXPRESSION for this test matched warnings in modules other
than the test line itself. Make the pass and fail regular expressions
specific to the file containing the lines they are testing.
This was missed by commit 7bbaa428 (Remove trailing whitespace from most
CMake and C/C++ code, 2012-08-13) which only removed trailing spaces,
not TABs.
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
