We aim to support building Qt examples that depend on Conan modules from command line, with minimal setup required by the user. The virtual[run]env generator seems to be ideal for this:

export QTDIR=<qt_dir>
conan install --generator virtualenv <src_dir>
activate.sh # Sets up CMAKE_PREFIX_PATH etc
cmake -D CMAKE_PREFIX_PATH=$QTDIR <src_dir>
cmake --build .
./example

export QTDIR=<qt_dir>
conan install --generator virtualenv <src_dir>
activate.sh # Sets up QMAKE_PATH
$QTDIR/qmake <src_dir>
make
./example

Extend the module recipes so that following environment variables are set:

QMAKEPATH (root of the module's mkspecs directory)
CMAKE_PREFIX_PATH (root of the module's lib directory)
QT_ADDITIONAL_PACKAGES_PREFIX_PATH (root of the module's lib directory)

and, on Windows,

PATH (pointing to module's bin folder)

Document for the examples in the respective modules
