Dear Cmake users,
I would like to add a custom command to be run on each target (in
fact on each target source file). Is there any way to do this with
cmake ? I found the ADD_CUSTOM_COMMAND function, but it must be
called for each target to be processed, and I am still missing a way
to get the source files list. Do you have any idea or advice ?
Best regards,
Julien
function( my_custom_add_executable NAME )
set( OPTIONS )
set( GENERATED_SOURCES )
foreach( arg ${ARGN} )
if( arg MATCHES "(WIN32|MACOSX_BUNDLE|EXCLUDE_FROM_ALL)" )
list( APPEND OPTIONS arg )
continue
endif( arg MATCHES "(WIN32|MACOSX_BUNDLE|EXCLUDE_FROM_ALL)" )
#TODO define the name of the generated file generated from ${arg}
in GENERATED
add_custom_command(
OUTPUT ${GENERATED}
COMMAND ${YOUR_COMMAND} ${SOME_FLAGS_GO_HERE} ${arg}
DEPENDS ${arg}
COMMENT "Generating ${arg}"
VERBATIM
)
list( APPEND GENERATED_SOURCES ${GENERATED} )
endforeach( arg )
# and here goes the actual add_executable call
add_executable( ${NAME} ${OPTIONS} ${GENERATED_SOURCES} )
endif( my_custom_add_executable )
You then simply replace all calls to add_executable with
my_custom_add_executable. Similarly you can proceed with add_library.
If you need to distinguish on source type (i.e. do something different
for all .c files than you do for all .idl files, you can do so easily
using a IF( ... MATCHES ... ) sequence in the FOREACH loop.
