Hi @PauloCarvalhoRJ -
these files are typically not packaged inside the package folders - they are generated on the consumer side with the CMakeDeps
generator (alongside CMakeToolchain
)
conan create .
If you are running this from a cloned copy of conan-center-index
, please inspect contents of the generators
folder inside the build folder - that's where Qt5Config.cmake should be found
Hello,
they are generated on the consumer side
I understand this, but I beg to disagree. Qt (as any other library that supports CMake) was supposed to be deployed with those. Furthermore, this forces me to build VTK with Conan (which I am currently able to). However, if I want to build VTK outside Conan, I'll be unable to use Conan's Qt. For me, this is odd.
Also, suppose I'm developing an application that uses Qt. During development I'll have to be able to configure the project outside Conan (e.g. in Qt Creator). Without the Find*.cmake
files, I expect trouble.

I think there is some confusion here.
As far as I'm aware, Qt does not come with the Find*.cmake
files - a packaged Qt comes with -config.cmake
files - which are a different mechanism to satisfy find_package()
calls in CMake.
The recipes in Conan Center do not currently ship with -config.cmake
files - but rather, the recipes need to express the same information the package_info()
method such that they can be consumed with any build system, not just CMake.
The recipes in Conan Center are meant to be consumed with Conan - Conan will generate the config files with a call to conan install
. Consuming the contents of the packages, you may have to do more work. You can probably edit the recipe and modify its behaviour to retain those files in the package contents - but then you'd have to handle the paths for every single dependency of Qt such that the find_package
call is successful.
Hi,
As far as I'm aware, Qt does not come with the Find*.cmake files
Along the precompiled one installed with the Windows installers avaiable on their website, you'll find FindQt5.cmake
under <install_dir>\lib\cmake\Qt5Core
.

Description
Hello,
I'm using Conan Center's Qt 5.x.x recipe (recipes/qt/5.x.x) to build Qt 5.15.14. The build seems to complete successfully, but I found that
FindQt.cmake
is not present in the final package directory. It is supposed to be at<conan cache dir>\b\qt<hash>\p\lib\cmake
. By the way, no otherFind*.cmake
file is being installed.I need this in order to build VTK with Qt support. VTK configuration with CMake (there is no Conan Center recipe for building it yet) needs these
Find*.cmake
files in order to work.thanks,
Paulo
