在带有 vcpkg static 导出的 CMake 项目中找不到“Qt5”

Question

I wanna create a project use VSCode+CMake+VCPKG(VTK+Qt5) And I still want to share my VCPKG depencies with teammate. So I export VCPKG.

When I try to find_package(Qt5 COMPONENTS Core REQUIRED) problem happened

By not providing "FindQt5.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Qt5", but
  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.

And I try to set(Qt5_DIR "{vckpg_root_path}\installed\x64-windows\share\qt5")

There is no Qt5Config.cmake to let cmake read!!

That's what inside.

How can I exactly use Qt5 And set include file directories in cmakelist.txt?

Answer 1

Finally, I found how to make it Add script in CMALKELIST.txt

cmake_minimum_required(VERSION 3.0.0)
set(VCPKG_DIR "C:/vcpkg/installed/x64-windows")
set(VCPKG_TARGET_TRIPLET "x64-windows"
      CACHE STRING "")
set(CMAKE_TOOLCHAIN_FILE "C:/vcpkg/scripts/buildsystems/vcpkg.cmake"
      CACHE STRING "")

and to add Qt compoment, cause Qt package is divide to many bit. So use COMPOMENTS with Qt package you want to include.

find_package(Qt5 COMPONENTS Core Widgets CONFIG REQUIRED)
if (${Qt5Core_FOUND})
    message("Found Qt " ${Qt5_VERSION})
else()
    message("Couldn't find Qt")
endif()
