I'm trying to make a very basic Qt5 application using CMake on Windows.
I used the documentation of Qt5 to use CMake[archived][doc.qt.io], and my main.cpp file just contains a main function.
My CMakeLists.txt is exactly:
cmake_minimum_required(VERSION 2.8.9)
project(testproject)
# Find includes in corresponding build directories
set(CMAKE_INCLUDE_CURRENT_DIR ON)
# Instruct CMake to run moc automatically when needed.
set(CMAKE_AUTOMOC ON)
# Find the QtWidgets library
find_package(Qt5Widgets)
# Tell CMake to create the helloworld executable
add_executable(helloworld hello.cpp)
# Use the Widgets module from Qt 5.
qt5_use_modules(helloworld Widgets)
When in MSysGit bash I enter
$ cmake -G"Visual Studio 11"
I get this output:
$ cmake -G"Visual Studio 11"

CMake Warning at CMakeLists.txt:11 (find_package):
By not providing "FindQt5Widgets.cmake" in CMAKE_MODULE_PATH this project
has asked CMake to find a package configuration file provided by
"Qt5Widgets", but CMake did not find one.
Could not find a package configuration file provided by "Qt5Widgets" with
any of the following names:
Qt5WidgetsConfig.cmake
qt5widgets-config.cmake
Add the installation prefix of "Qt5Widgets" to CMAKE_PREFIX_PATH or set
"Qt5Widgets_DIR" to a directory containing one of the above files. If
"Qt5Widgets" provides a separate development package or SDK, be sure it has
been installed.
CMake Error at CMakeLists.txt:17 (qt5_use_modules):
Unknown CMake command "qt5_use_modules".
-- Configuring incomplete, errors occurred!
Do you have any ideas?
After the lines
cmake_minimum_required(VERSION 2.8.9)
project(testproject)
add
set (CMAKE_PREFIX_PATH "C:\\Qt\\Qt5.0.1\\5.0.1\\msvc2010\\")
This solves the problem.
