I am trying to compile a github project for Qt, using CMake. Here is the settings:
![alt text](image url)
But I cannot setup a correct QT path: Qt5_DIR-NOTFOUND
Here is the outcome message:
CMake Error at CMakeLists.txt:32 (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 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.
I even setup Qt in PATH:
I always got Qt5_DIR-NOTFOUND as feedback. What should I do in order to overcome this error ?
The PATH environment variable won't help there.
Add the installation prefix of "Qt5" to CMAKE_PREFIX_PATH
Define it to point to your Qt 5 installation as suggested when calling cmake.
Or if you also have Qt Creator, just build it using it.
Yes, I have used Qt Creator to compile with CMake, specifically, I have loaded CMakeLists.tzt into Qt Creator, but there I have another troubles:

I guess the CMake way it is the easy one.
Your build started correctly.
Qt Creator uses cmake since it's a cmake project. The main difference is that the paths for Qt are pre-configured so you do not have to worry about that.
What is failing here is the rc call. How does your CMakeFile.txt look like ?

In fact, is about this CMakeLists.txt: https://github.com/cnr-isti-vclab/meshlab/blob/master/src/CMakeLists.txt
Any hint will be very helpful to me.
It's the rc part that fails. Did you a fresh build from start ?
@SGaist Thank you a lot. I have succeeded into compiling that project, using CMake and VS2017.
You're welcome !
What did you do to succeed ?
I have generated VS2017 solution file using CMake, but I get out Qt option, so I am not using Qt right now, just VS2017. Now, I can compile, run and debug reliable this project. Thank you a lot for your support.
And another information for those who have the same issue, I noticed that CMake chooses Qt5_DIR with this values:
Hope it helps.
