After the first time running sudo cmake, you will end up with directories owned by root, so subsequent non-sudo calls to cmake may fail, similarly to why make is failing without sudo. If you destroy and recreate your build directory and then run cmake without sudo you should no longer need it at any point, and if you do, that suggests something is broken somewhere else, probably by overuse of sudo as well.
Also, try using -DPYTHON_EXECUTABLE=/usr/bin/python3, not /usr/bin/python3.7, and you will probably not need any more of the other Python flags.
As said by Kremitzki, if you ran sudo cmake at least once, it’s possible that the created directories and files will be owned by root, so you cannot access them by the regular pi user anymore, unless you use sudo again. This is the problem with using sudo indiscriminately. It should only be used when necessary.
Another issue is if the directories that you created were done by sudo. Again, bad.
sudo git clone ...
sudo mkdir freecad-source
And yes, please post the error messages to confirm this is just a permission issue and not something else.
I would advise you to re-create the directories with your regular user and try again. However, since you mentioned it takes a long time to compile, well, do it when you have the chance.
Ah ok, so, no it doesn’t show no any cone. Just a kind of screenshot as the picture shows.
You should get something like this.
Super cool!
The biggest problem I guess is to make Qt cooperate with Coin3d because with recent Qt5 versions a special attribute must be set. When I first tested FreeCAD with Qt 5.12 I had a similar problem where Coin3d couldn’t get the current OpenGL context. After setting Qt::AA_UseDesktopOpenGL things started to work again.
Now that you have compiled your own FreeCAD binaries you can try if this helps you, too. Therefore go to src/Gui/Application.cpp and search for “Qt::AA_UseDesktopOpenGL”. Change the line above from
#if (QT_VERSION >= QT_VERSION_CHECK(5, 12, 0))
to
#if (QT_VERSION >= QT_VERSION_CHECK(5, 11, 0))
and rebuild FreeCADGui. It’s sufficient to invoke make FreeCADGui/fast
There are some further Qt attributes dealing with OpenGL, see https://doc.qt.io/qt-5/qt.html
Qt::AA_UseOpenGLES, Qt::AA_UseSoftwareOpenGL and Qt::AA_ShareOpenGLContexts (already used)
According to https://doc.qt.io/qt-5/windows-requirements.html the attributes Qt::AA_UseDesktopOpenGL, Qt::AA_UseOpenGLES and Qt::AA_UseSoftwareOpenGL are mutual exclusive and instead of changing the source code you can set the environment variable QT_OPENGL.
Setting Qt::AA_UseDesktopOpenGL is equivalent to QT_OPENGL=desktop
Setting Qt::AA_UseOpenGLES is equivalent to QT_OPENGL=angle
Setting Qt::AA_UseSoftwareOpenGL is equivalent to QT_OPENGL=software
NOTE: This is written on the page for requirements on Windows and I don’t know in how far this applies to other platforms!
Your explations helped me a lot, thanks guys.
I’ve over abused of sudo indeed… by typing sudo -i as first commande before starting last compilations, then sudo again later. My bad 
Ok, hence no more sudo now:
I’ve made backup copies of freecad-source and freecad-build directories (you were right guys, some files were owned by pi user, some others by root user)
then I’ve deleted freecad-build directory then created a new one (empty directory I mean)
mkdir freecad-build
then changed owner of files in freecad-source directory
sudo chown -R pi freecad-source
then cmake
cd freecad-build/
cmake -DBUILD_QT5=ON -DPYTHON_EXECUTABLE=/usr/bin/python3 -DCMAKE_BUILD_TYPE=Debug ../freecad-source
No errors with cmake,.
Then make, still 2 hours compiling.
make -j4
No warnings.
I ran FreeCAD, still crashing at creating of a new document.
Ok, so
pi@raspberrypi:~/freecad-source/src/Gui $ nano Application.cpp
Then I’ve change QT version 5,12,0 → 5, 11,0
then
pi@raspberrypi:~/freecad-build $ make FreeCADGui/fast
But Freecad still crash with same error:

Also, your version of FreeCAD is a bit old. Currently the master tree is in commit 18374, so you should test with the latest code.

Then cmake and make again.

So to hunt down the problem we have to find out why setting up the GL context fails. Therefore, next step is to set the environment variable COIN_GL_NO_CURRENT_CONTEXT_CHECK
export COIN_GL_NO_CURRENT_CONTEXT_CHECK=1
before starting FreeCAD. Then we can see if a current context is set or not.

FYI sometimes I’ve got another error below when running ./FreeCAD. Freecad even don’t start this time, the last time this error occured while opening “about Freecad” menu.

pi@raspberrypi:~/freecad-build/bin $
One comment again: when I had updated the source code with “pull git”, I’ve got an error message about ‘Application.cpp’ file, because of the modification QT_VERSION_CHECK( 5, 12, 0) → 5, 11, 0. So, I’ve modified the file again with QT 5, 12, 0 only during the update. Then I’ve set again with QT 5, 11, 0 once pull git achieved. However, Before this last change, I’ve started Freecad to test, but the clipboard info mentioned 'Qt version/ 5.11.3.
I mean, now no matter if I set Qt 5,12,0 or Qt 5, 11, 0 in Application.cpp, Freecad info always mention QT version: 5.11.3.
Strange or not?

Mmm. Honey.
Anyway, how are you setting the variable? Are you using some file that you find in Raspbian? That’s not needed.
To test a single environmental variable, you can set it in the terminal, before running your command.
export COIN_GL_NO_CURRENT_CONTEXT_CHECK=1
./FreeCAD
Or in the same line
COIN_GL_NO_CURRENT_CONTEXT_CHECK=1 ./FreeCAD
You can do this as well before launching the debugger, or inside the debugger.
(gdb) set env COIN_GL_NO_CURRENT_CONTEXT_CHECK 1
(gdb) run
To be honest right now I’m eating some chocolate paste 
Yes that’s what I did, from bash.
I’ve tried it again, this time inside debugger as you say:

seem different with previous ones. I have no idea if it does matter…
By setting the env. variable this check was done: https://bitbucket.org/Coin3D/coin/src/ab8d0e47a4de3230a8137feb39c142d6ba45f97d/src/glue/gl.cpp#lines-2354
Because the assert() didn’t fail it means that at least a current OpenGL context is set.
Because the last function call is glxglue_init() I think the crash only can happen here: https://bitbucket.org/Coin3D/coin/src/ab8d0e47a4de3230a8137feb39c142d6ba45f97d/src/glue/gl_glx.cpp#lines-486 where glXGetCurrentDisplay is a function pointer to XDefaultScreenOfDisplay.
One comment again: when I had updated the source code with “pull git”, I’ve got an error message about ‘Application.cpp’ file, because of the modification QT_VERSION_CHECK( 5, 12, 0) → 5, 11, 0. So, I’ve modified the file again with QT 5, 12, 0 only during the update.
You can revert your changes again as it appears that these settings are Windows-specific.
When searching for “XDefaultScreenOfDisplay” and “crash” there I found this hit:
https://github.com/flathub/org.freecadweb.FreeCAD/issues/11
Can you try to set the env. variable
export QT_QPA_PLATFORM=xcb
Thanks Werner for you attention and explanations,

Now I have no idea what else you can try. Maybe it’s a graphic driver problem.
Ok, thanks for your help anyway, much appreciated.
I’m not a developper, so I have not much idea than you of course.
However I have the RPI4 next to me, so I could:
- try to compile Freecad 0.19 with Py2/Qt4?
- try to compile Freecad 0.16 with Py2/Qt4 ? (because Papy told he ran 0.16 on RPI4 with success before this version was replaced by 0.18 in repo
https://forum.freecadweb.org/viewtopic.php?f=12&t=37314#p317122 (french)
I would like to see that by my own eyes, it could be a way to maybe track the bug?)) - try to compile Freecad’s pivy in order to use it instead of pivy lib?
Could you guys tell me your opinion if such tries would make sens?
- try to compile Freecad 0.19 with Py2/Qt4?
Yes, this should be possible. The current master branch still supports Py2 and Qt4.
