Ben Boeckel 29c3edb87a Avoid if() quoted auto-dereference
When testing CMAKE_<LANG>_COMPILER_ID values, do not explicitly
dereference or quote the variable. We want if() to auto-dereference the
variable and not its value. Also replace MATCHES with STREQUAL where
equivalent.

c28715b try_compile: Add COPY_FILE_ERROR option to capture failure

Brad King c28715b16c try_compile: Add COPY_FILE_ERROR option to capture failure
When the COPY_FILE operation fails optionally capture the error message
with a COPY_FILE_ERROR option instead of reporting the error
immediately.  This gives callers a chance to do something else or report
the error.

Teach the RunCMake.try_compile test to cover bad argument combinations
involving COPY_FILE_ERROR.  Teach the TryCompile test to cover the case
of a COPY_FILE error message captured by COPY_FILE_ERROR.

Brad King 290857bb03 try_compile: Escape CMAKE_<lang>_FLAGS in test projects (#14268)
If CMAKE_<lang>_FLAGS contains quotes or other CMake language characters
they must be escaped when written into the generated CMakeLists.txt file
so that the test project parses them properly.

Teach the TryCompile test to cover this case by adding a flag with
quotes into CMAKE_C_FLAGS during a C language try_compile.

Brad King 482f1122ad try_compile: Add signature to allow multiple SOURCES
Extend the signature

 try_compile(RESULT_VAR <bindir> <srcfile> ...)

to allow multiple sources as

 try_compile(RESULT_VAR <bindir> SOURCES <srcfile>... ...)

Process the sources to generate a CMakeLists.txt that enables all needed
languages.

Teach the TryCompile test to try cases with two sources of the same
language and of mixed languages.  Teach RunCMake.try_compile to cover
error cases for the signature.

Kitware Robot 9db3116226 Remove CMake-language block-end command arguments
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

Kitware Robot 77543bde41 Convert CMake-language commands to lower case
Ancient CMake versions required upper-case commands.  Later command
names became case-insensitive.  Now the preferred style is lower-case.

Run the following shell code:

cmake --help-command-list |
grep -v "cmake version" |
while read c; do
    echo 's/\b'"$(echo $c | tr '[:lower:]' '[:upper:]')"'\(\s*\)(/'"$c"'\1(/g'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
xargs -0 sed -i -f convert.sed &&

Kitware Robot 7bbaa4283d Remove trailing whitespace from most CMake and C/C++ code
Our Git commit hooks disallow modification or addition of lines with
trailing whitespace.  Wipe out all remnants of trailing whitespace
everywhere except third-party code.

git ls-files -z -- \

 '*.c' '*.cmake' '*.cpp' '*.cxx' \
 '*.el' '*.f' '*.f90' '*.h' '*.in' '*.in.l' '*.java' \

Brad King b3efdb58d5 CheckCCompilerFlag: Strict signature of 'main' (#11615)
Use "int main(void)" instead of just "int main()" so that compiling with
"gcc -Werror=strict-prototypes" works.  Test this check using the flags
"-Werror -Wstrict-prototypes" to work with old GCC versions.

Brad King 2b3eee4646 Avoid PathScale cmd-line bug in TryCompile test
The PathScale compiler silently accepts unknown options that start in
more than one '-':

  $ touch foo.c
  $ pathcc -c foo.c --junk
  $ echo $?
  0
  $ pathcc -c foo.c ---junk
  $ echo $?
  0
  $ pathcc -c foo.c -junk
  pathcc ERROR parsing -junk: unknown flag
  $ echo $?
  2

We teach the TryCompile to pass a bogus flag with only one '-' instead
of three '-'s for this compiler.

Brad King 997ae66cbb Fix CHECK_(C|CXX)_COMPILER_FLAG macro test
The flag "-_this_is_not_a_flag_" was not rejected by GCC 4.0 on older
Mac OS X.  We now use "---_this_is_not_a_flag_" instead, which will
hopefully be rejected by all compilers.

Brad King 42857c747e Test CHECK_(C|CXX)_COMPILER_FLAG macros
This teaches the TryCompile test to check that the compiler flag check
macros correctly reject a bad flag.  See issue #9516.

Brad King 80c947b397 No /fast targets in try_compile project mode
The try_compile command builds the cmTryCompileExec executable using the
cmTryCompileExec/fast target with Makefile generators in order to save
time since dependencies are not needed.  However, in project mode the
command builds an entire source tree that may have dependencies.
Therefore we can use the /fast target approach only in one-source mode.

Brad King 73de2362dd Fix recursive try_compile calls
When building an entire source tree with try_compile instead of just a
single source file, it is possible that the CMakeLists.txt file in the
try-compiled project invokes try_compile.  This commit fixes propagation
of language-initialization results from the outer-most project into any
number of try-compile levels.

Brad King 1a159bbf33 Test try_compile project mode
The try_compile command project mode builds an entire source tree
instead of one source file.  It uses an existing CMakeLists.txt file in
the given source tree instead of generating one.  This commit creates a
test for the mode in the TryCompile test.

-TRY_RUN in crosscompiling mode: copy the created executables to

Alexander Neundorf eddf1cf39f ENH: improve TRY_RUN() for crosscompiling: instead of just failing, it now
creates two cache variables, one for the RUN_RESULT, one for the RUN_OUTPUT
(if required), which can be set or preset by the user. It has now also two
new arguments: RUN_OUTPUT_VARIABLE and COMPILE_OUTPUT_VARIABLE (the old
OUTPUT_VARIABLE merges both), so if only COMPILE_OUTPUT_VARIABLE is used the
run time output of the TRY_RUN is unused and the user doesn't have to care
about the output when crosscompiling. This is now used in FindThreads.cmake,
CheckC/CXXSourceRuns.cmake and TestBigEndian.cmake, which used the output
only for the logfile (compile output is still there). Test/TryCompile/ now
also tests the behaviour of OUTPUT_VARIABLE, RUN_OUTPUT_VARIABLE and
COMPILE_OUTPUT_VARIABLE.
