You mean something like this?
if("${ARGN}" STREQUAL "")
set(_lang C)
elseif("${ARGN}" MATCHES "^LANGUAGE;([a-zA-Z]+)$")
set(_lang "${CMAKE_MATCH_1}")
else()
message(FATAL_ERROR "Unknown arguments:\n ${ARGN}\n")
endif()
[...]
if("${_lang}" STREQUAL "C")
[...]
elseif("${_lang}" STREQUAL "CXX")
[...]
else()
message(FATAL_ERROR "Unknown language:\n ${_lang}\nSupported languages:
C, CXX.\n")
endif()
Is the "MATCHES" using a list as a string "safe"? Or is there another way to
simplify it?
Otherwise I can do the same using list(LENGTH) and list(GET) instead of ARGC
and ARGV4/5, but it looks more complicated.
Cheers,
Daniele
