Refactor cmake scripts

[ahmedyarub]

1- Use Glob to (greatly) lower CMake's file size
2- Build one of the examples using CMake (later I'll add CMake scripts for building the other examples)
3- Move unit-tests and plugins outside the main source folder to avoid picking them up by GLOB

This has been fully tested. I'm open to any suggestions :)

Very cool !
Migrating makefile to CMake for examples is very useful !

But c/kubernetes/CMakeLists.txt bases on the template file:
https://github.com/OpenAPITools/openapi-generator/blob/master/modules/openapi-generator/src/main/resources/C-libcurl/CMakeLists.txt.mustache, (actually the *.c and *.h lists are generated in CMakeLists.txt)

And I don't recommend moving "unit-test" and "plugins" directories outside the main source folder kubernetes because

• "unit-test" comes from https://github.com/OpenAPITools/openapi-generator/tree/master/modules/openapi-generator/src/main/resources/C-libcurl
• "plugins" is a component of kubernetes configuration.

Could you please add your code to the template file ?

[ahmedyarub]

Sure I'll do that later today

libwebsockets, yaml and examples are not needed by https://github.com/OpenAPITools/openapi-generator/blob/master/modules/openapi-generator/src/main/resources/C-libcurl/CMakeLists.txt.mustache. They are only used by kubernetes client C.

I went ahead and downloaded all the requirements for regenerating the C client for k8s, trying to understand how the CMake script were customized exactly by the generator, and it looks like additions were made manually in a PR like this #9. In this PR you can see that some .c files were added manually to the SRCS variable since the generator does not know about these files. I was trying to do exactly the same. So the question now is: what is the accepted solution for customizing the template? by adding changes manually to this repo? Or may I suggest including optional CMake scripts in multiple places (ex: in the beginning of the file, before find_package(), at the end of the file, etc...) so that each generated client can add its own scripts without editing the original template?

For this PR:
1- Use Glob to (greatly) lower CMake's file size
2- Build one of the examples using CMake (later I'll add CMake scripts for building the other examples)
3- Move unit-tests and plugins outside the main source folder to avoid picking them up by GLOB

I only suggest addressing the # 2 (Build one of the examples using CMake) for now.
The # 1 and # 3 are not needed because it will introduce complexity and conflict with openapi-generator/c-libcurl

But I also agree the solution including optional CMake scripts in multiple places is a good solution because this repo will not need update manually each time re-generating the C client. e.g. add below files
( config/kube_config_model.c
config/kube_config_yaml.c
config/kube_config_util.c
config/kube_config.c
config/incluster_config.c
config/exec_provider.c
config/authn_plugin/authn_plugin_util.c
config/authn_plugin/authn_plugin.c
watch/watch_util.c
websocket/wsclient.c
websocket/kube_exec.c)

So it's up to you: if you want to merge this PR quickly, then only need address # 2; if you want to re-organize the CMakefiles in upstream repo (openapi-generator/c-libcurl), please try it. Thank you.

I will reorganize the CMake files and create new PR's within the next days. Thank you.
