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 && rm convert.sed

macro(CHECK_INCLUDE_FILE_CXX INCLUDE VARIABLE)
Check*: Add compatibility hack for old VXL code The cleanup in commit 4f2fcce4 (Check*: Allow result variables to contain regex special characters, 2014-07-31) broke old VXL code that abuses the old "if(MATCHES)" implementation by using SET( ${VARIABLE} ${VARIABLE} ) to reset a check result variable. Add a compatibility hack to the CheckFunctionExists, CheckIncludeFileCXX, and CheckSymbolExists modules to re-run their checks when the result variable is set to its own name. Use STREQUAL instead of MATCHES so that special characters still work.
