Build Qt/cmake based project in GitHub Actions-CodePudding

I'm using Qt 5.12.11 in my project. As I wanted to use the software both on linux and win, I selected gcc compiler (I use MSYS2, so gcc is 10.3.0). The local build is ok both for linux and win, but the build via GitHub Actions fails on finding the qt (no matter if I set CMAKE_PREFIX_PATH or Qt5_DIR or not).

So this is where I'm stuck for a while. Has anyone encountered such problems or have any ideas on it?

github action looks like

name: Build

on:
  push:
    branches: [ master ]
  pull_request:
    branches: [ master ]

env:
  BUILD_TYPE: Release

jobs:
  build:
    runs-on: windows-latest
    defaults:
        run:
            shell: msys2 {0}

    steps:
      - uses: msys2/setup-msys2@v2
        with:
            install: mingw-w64-x86_64-toolchain
            msystem: mingw64
            release: false

      - name: Install Qt
        uses: jurplel/install-qt-action@v2
        with:
          version: '5.12.11'
          host: 'windows'
          target: 'desktop'
          arch: 'win64_mingw73'
          dir: '${{github.workspace}}/qt/'
          install-deps: 'true'

      - name: List files in Qt
        run: find ${{env.Qt5_Dir}}

      - uses: actions/checkout@v2

      - name: Configure CMake
        run: cmake -DCMAKE_BUILD_TYPE=${{env.BUILD_TYPE}} -DCMAKE_PREFIX_PATH="${{env.Qt5_Dir}}/lib/cmake/" -DQt5_DIR=${{env.Qt5_Dir}}/lib/cmake/Qt5/ -G "CodeBlocks - MinGW Makefiles" -B '${{github.workspace}}'/build

      - name: Build
        run: cmake --build '${{github.workspace}}'/build --target RePr

I've also tried -DCMAKE_PREFIX_PATH="${{env.Qt5_Dir}}/lib/cmake/Qt5/" but it didn't help. :( if I set the CMAKE_PREFIX_PATH directly from the cmakelists I observe the same behavior.

CMakeLists on which it fails is quite simple and usual (it's a nested package that uses qt, so don't be confused about different cmakelists project and build target)

cmake_minimum_required(VERSION 3.14)
project(RePr_controller)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)
set(CMAKE_AUTOUIC ON)

set(QT_VERSION 5)
set(REQUIRED_LIBS Core Gui Widgets)
set(REQUIRED_LIBS_QUALIFIED Qt5::Core Qt5::Gui Qt5::Widgets)

add_library(${PROJECT_NAME} main_window.cpp main_window.h main_window.ui resources/resources.qrc)
add_dependencies(${PROJECT_NAME} FacadeLib)
target_link_libraries(${PROJECT_NAME} FacadeLib Utils)

find_package(Qt${QT_VERSION} COMPONENTS ${REQUIRED_LIBS} REQUIRED)
target_link_libraries(${PROJECT_NAME} ${REQUIRED_LIBS_QUALIFIED})

Messaging the CMAKE_PREFIX_PATH directly from the cmakelists returns

D:/a/RePr/RePr/qt/Qt/5.12.11/mingw73_64/lib/cmake/

qt5 is here

D:/a/RePr/RePr/qt/Qt/5.12.11/mingw73_64/lib/cmake/Qt5/Qt5Config.cmake

finally, I got this message from configuring step

CMake Error at Controller/CMakeLists.txt:17 (find_package):
  By not providing "FindQt5.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Qt5", but
-- Configuring incomplete, errors occurred!
See also "D:/a/RePr/RePr/build/CMakeFiles/CMakeOutput.log".
  CMake did not find one.

  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.
