Cannot install qt 6.7.0 prebuilt binary on Windows about conan HOT 5 OPEN

Hi @ABBAPOH

Thanks for your report.

I have been able to reproduce, first I also got the same "Missing binary" error, and then:

(conan2_310) λ conan graph explain --requires=qt/6.7.0 -s compiler.cppstd=17 -o qt*:qtdeclarative=False -o qt*:qtdoc=False -o qt*:qttools=False -o qt*:qttranslation=False

======== Computing dependency graph ========
ERROR: qt/6.7.0: Error in configure() method, line 229

while calling '_enablemodule', line 217
        setattr(self.options, mod, True)
        ConanException: Incorrect attempt to modify option 'qtdeclarative' from 'False' to 'True'

This looks like a bug in the recipe in ConanCenter, not in Conan itself, I'll try to have a look.

From this comment #10104 (comment) it seems that one cannot modify props here https://github.com/conan-io/conan-center-index/blob/master/recipes/qt/6.x.x/conanfile.py#L215

Hi @ABBAPOH , thank you for reporting this.
We have located the issue in the Conan Center recipe. Apologies for this - we will be more careful in the future.

I get the same issues with Linux. All the dependency options affect the package ID.

Hi @glennaycock - thanks for reporting this.

Looking to sort this out - however it's not ideal.
We can set essential_modules=False for everyone, but that probably means reduced functionality
Or we can set essential_modules=True, but we maintain too many qt versions and this has a severe impact on our CI.

While we address this, in the meantime:

• if you pass -o "qt/*:essential_modules=False" and are using a configuration that matches our CI, you should get the same binaries that we currently have published
• pass -o "qt/*:essential_modules=True" and --build=missing

It really does depend on what your needs are with regards to the components that qt should have been built with
