You can not run a script by "./script" on Windows and you need to invoke it
with "perl ./script"

Sorry for not being more precise (maybe not so clear when you're not familiar
with CMake in WebKit).

E.g. at [1] the following line calls makeprop.pl with the --preprocessor
argument "cl.exe /nologo /EP":
COMMAND ${PERL_EXECUTABLE} -I${WEBCORE_DIR}/bindings/scripts
${WEBCORE_DIR}/css/makeprop.pl --defines
"${FEATURE_DEFINES_WITH_SPACE_SEPARATOR}" --preprocessor
"${CODE_GENERATOR_PREPROCESSOR}"
grep for CODE_GENERATOR_PREPROCESSOR in the CMakeLists.txt and *.cmake files
should show up all other uses.
