Adding qt project generation fix #7784

[MartinDelille]

PR checklist

• Read the contribution guidelines.
• Ran the shell script under ./bin/ to update Petstore sample so that CIs can verify the change. (For instance, only need to run ./bin/{LANG}-petstore.sh and ./bin/security/{LANG}-petstore.sh if updating the {LANG} (e.g. php, ruby, python, etc) code generator or {LANG} client's mustache templates). Windows batch files can be found in .\bin\windows\.
• Filed the PR against the correct branch: 3.0.0 branch for changes related to OpenAPI spec 3.0. Default: master.
• Copied the technical committee to review the pull request if your PR is targeting a particular programming language.

Description of the PR

I would like to fix #7784 by adding client.pri generation. This is a work in progress but I open this PR to address some problem I have with its implementation.

For the Pet Store example, the resulting file should look like this:

QT += network

HEADERS += \
	$${PWD}/SWGApiResponse.h \
	$${PWD}/SWGCategory.h \
	$${PWD}/SWGHelpers.h \
	$${PWD}/SWGHttpRequest.h \
	$${PWD}/SWGModelFactory.h \
	$${PWD}/SWGObject.h \
	$${PWD}/SWGOrder.h \
	$${PWD}/SWGPet.h \
	$${PWD}/SWGPetApi.h \
	$${PWD}/SWGStoreApi.h \
	$${PWD}/SWGTag.h \
	$${PWD}/SWGUser.h \
	$${PWD}/SWGUserApi.h

SOURCES += \
	$${PWD}/SWGApiResponse.cpp \
	$${PWD}/SWGCategory.cpp \
	$${PWD}/SWGHelpers.cpp \
	$${PWD}/SWGHttpRequest.cpp \
	$${PWD}/SWGOrder.cpp \
	$${PWD}/SWGPet.cpp \
	$${PWD}/SWGPetApi.cpp \
	$${PWD}/SWGStoreApi.cpp \
	$${PWD}/SWGTag.cpp \
	$${PWD}/SWGUser.cpp \
	$${PWD}/SWGUserApi.cpp

Here are the tasks to do:

• Add optionalProjectFile switch to the command line
• Generate client.pri
• Add test

As you can see, the tests are failing:
https://travis-ci.org/swagger-api/swagger-codegen/builds/350829855#L2556

What am I missing?

[stkrwork]

you are missing the mustache file

[stkrwork]

also check the processOpts function

[MartinDelille]

travis build failed but it doesn't seems to be related to my modification, am I right?

Now I just need to fill Project.mustache file but since I'm new to mustache, someone could give me a clue how to list the headers and sources files generated?

[stkrwork]

QT += network

HEADERS += \
{{#operations}}
	$${PWD}/{{classname}}.h \
{{/operations}}
{{#models}}
{{#model}}
	$${PWD}/{{classname}}.h \
{{/model}}
{{/models}}

SOURCES += \
{{#operations}}
	$${PWD}/{{classname}}.cpp \
{{/operations}}
{{#models}}
{{#model}}
	$${PWD}/{{classname}}.cpp \
{{/model}}
{{/models}}

I think, but i am not sure

[MartinDelille]

Ok I implemented the mustache part. Let me know if it looks good to you!

Ping @ravinikam @stkrwork @fvarose
