I ran into this problem using Visual Studio 2008 and wrote up a macro to
generate the add_custom_command for each idl file. The function will rerun the
build command whenever the idl file is modified. There is very little
documentation for working with idl files online, so I hope this helps you.
Variables:
IDL_H_FILES: Generated header files
IDL_C_FILES: Generated C files
IDL_OUTPUT_LOC: The location where you want the build products to be
placed
idl_file1.idl ...: A list of idl files that you want to run the macro
against.
#IDL_COMPILE( IDL_H_FILES_VAR IDL_C_FILES_VAR IDL_OUTPUT_LOC_VAR idl_file1.idl
idl_file2.idl ... )
MACRO( IDL_COMPILE IDL_H_FILES_VAR IDL_C_FILES_VAR IDL_OUTPUT_LOC )
IF( WIN32 )
SET( ${IDL_H_FILES} "" )
SET( ${IDL_C_FILES} "" )
FOREACH( INDEX ${ARGN} )

Subject: [CMake] Auto detect IDL changes
Greetings all,
I've been deploying Cmake into our project for the past 2-3 months and just up
with a problem I was unable to resovle so far.
As part of the work we do, during Cmake execution, we also compile our C++ IDLs.
I've managed to come up with a clean EXECUTE_PROCESS code that will run this on
all OSs.
The problem is that IDLs do not change on a frequent basis and the fact that
these are added to the cmake makes it very generic, but forces a full build
with every build request.
Is there any way to come up with a way to identify the case where IDLs are
changed only than execute the compilation code?
Thanks in Advance,
Avner Cohen.
