Hi All,
I have one issue connected with generated code.
What is recommended way to proceed with generators which provides
source which is dynamic?
The setup looks like: generator has some input, and depending on this
input files are generated.
>From cmake point of view I need only this list of source files to
create library.
Generator is providing simple command to generate such a list.
During cmake phase, I'm calling generator to generate list.cmake with
list of source file,
then such a list is included, and configuration is generated. Source
file are marked as generated, and appropriate
ADD_CUSTOM_COMMAND(OUTPUT list) is registerd.
In lifecycle cmake -> make -> edit-input_files -> make -> edit ... make
everything works smooth with one remark, If you will edit input files
in a way that new source file will be introduced, then regeneration is
not enough, I need to regenerate configuration,
with current approach it looks like:
edit-input-adding-new-file ->
make-step1-generate: will regenerate the code + regenerate
cmakelist - since new file is there
make-step2-compile-sources:
make-step3-linking - will fail since new file is not added to
configuration,
with next run of make, cmake --check-build-system will recognize
changes in cmakelist and configuration will be regenerated, and build
will be successfull (if code changes was smart enough:) )
The question is if there are some hooks to cmake --check-build-system
that also additionaly my generate --cmake action will be called? (to
regenerate cmakelist which holds list of files)
Or maybe my approach is wrong?
thanks in advance
Lukasz
