[question] how to use qt/5.15.2@ recipe?

[AndreyMlashkin]

I am trying to switch from the obsolete bincrafters recipe to qt/5.15.2@
As starting point, I take a test_package/conanfile.py

There is a "qt" generator used

generators = "qt", "cmake", "cmake_find_package_multi", "qmake"

If I try to use this generator in my recipe, I get the following error:

ERROR: Invalid generator 'qt'. Available types: txt, gcc, compiler_args, cmake, cmake_multi, cmake_paths, cmake_find_package, cmake_find_package_multi, qmake, qbs, scons, visual_studio, visual_studio_multi, visual_studio_legacy, xcode, ycm, virtualenv, virtualenv_python, virtualbuildenv, virtualrunenv, boost-build, pkg_config, json, b2, premake, make, deploy, markdown, CMakeToolchain, CMakeDeps, MSBuildToolchain, MesonToolchain, MSBuildDeps, QbsToolchain, msbuild, VirtualEnv, AutotoolsDeps, AutotoolsToolchain, AutotoolsGen, BazelDeps, BazelToolchain

I use

Conan version 1.37.2

Without this generator, I get the following error in both test_package and in my recipe:

  Could not find a package configuration file provided by "Qt5" with any of
  the following names:

    Qt5Config.cmake
    qt5-config.cmake

  Add the installation prefix of "Qt5" to CMAKE_PREFIX_PATH or set "Qt5_DIR"
  to a directory containing one of the above files.  If "Qt5" provides a
  separate development package or SDK, be sure it has been installed.```

These errors are unexpected: "qt" generator should be available and Qt5::foo targets should be available
Can you please send your conanfile, profile, the command you are executing, and the full output ?

I have cleaned the local cache and it seems, the problem is gone, thank you!

I have another issue, not really related:
is there already support for Qt5:X11Extras module?

[ericLemanissier]

the module can be built with option -o qt:qtx11extras=True, but it currently be consumed only from qmake projects because the recipe does not yet create the cmake targets for this module

[AndreyMlashkin]

Thanks a lot!

I have opened a PR about adding x11 extras
