Fix rpath-link flag for SunPro C++ 5.11 on Linux Commit 82c081ba (Fix rpath-link flag for SunPro C++ on Linux, 2009-07-13) taught CMake to pass '-rpath-link' because SunPro C++ 5.9 does not support '-Wl,'. Now SunPro C++ 5.11 does not recognize the option without using '-Wl,'. Detect whether to use '-Wl,' based on the output of "sunCC -flags". 2010-06-07 18:13:33 +04:00			`# Sun C++ 5.9 does not support -Wl, but Sun C++ 5.11 does not work without it.`

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 2012-08-13 21:47:32 +04:00			`set(CMAKE_EXE_EXPORTS_CXX_FLAG "--export-dynamic")`
