[SOLVED] Installing Qt5Svg with Conan

Issue

So I'm trying to port this project I've been working on from qmake to cmake. I also plan to get my qt dependencies through Conan and get a CI service going. Getting most of the qt libraries was fairly easy using qt/5.12.4@bincrafters/stable. Except one. For some reason, the Qt5Svg module is not included with this package and I couldn't find a good solution for this so I've hit a dead end. Bellow are the error messages and the relevant cmake files.

Error message

[CMake] CMake Error at src/analysis_tool/CMakeLists.txt:33 (find_package):
[CMake] By not providing "FindQt5Svg.cmake" in CMAKE_MODULE_PATH this project has
[CMake] asked CMake to find a package configuration file provided by "Qt5Svg", but
[CMake] CMake did not find one.

All the other modules seem to be installing just fine (Qt5Core Qt5Widgets etc) and I can find them in the .conan folder but not the Qt5Svg one. Thanks for taking the time to read through this.

Solution

You need to provide and option to build qtsvg with qt package. Your conan_cmake_run should look as follow:

cmake_minimum_required(VERSION 3.8)
project(codego)

set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)
set(CMAKE_AUTOUIC ON)

set(CMAKE_AUTOUIC_SEARCH_PATHS ui)

if(NOT EXISTS "${CMAKE_BINARY_DIR}/conan.cmake")
    message(STATUS "Downloading conan.cmake from https://github.com/conan-io/cmake-conan")
    message(${CMAKE_BINARY_DIR};)
    file(DOWNLOAD "https://github.com/conan-io/cmake-conan/raw/v0.15/conan.cmake" "${CMAKE_BINARY_DIR}/conan.cmake")

  endif()

  include(${CMAKE_BINARY_DIR}/conan.cmake)

  conan_add_remote(
    NAME
    bincrafters
    URL
    https://api.bintray.com/conan/bincrafters/public-conan)

conan_cmake_run(
       REQUIRES qt/5.14.1@bincrafters/stable
       OPTIONS qt:qtsvg=True
       BASIC_SETUP
       CMAKE_TARGETS
       BUILD missing
)

EDIT: I used qt 5.14.1 as 5.12.4 was failing to build on my osx machine due to some outdated packages. Now when I do ls:

ls ~/.conan/data/qt/5.14.1/bincrafters/stable/package/<package_id>/lib/cmake/

gives me Qt5Svg among folders
