Hello. The issue is missed TCL and TK. They are necessary for BUILD_MODULE_DRAW. You can disable using of them from USE_TK USE_FreeType parameter.
But if you working on windows, I recommend, to use 3rd party from https://github.com/Open-Cascade-SAS/OCCT/releases/tag/V7_8_0
You will need to download 3rd party folder. And during configure"-D3RDPARTY_DIR=..."
If you are working from linux, install from distribution repo.
An extra information, in that month VCPKG will be integrated into OCCT.
Best regards, Dmitrii.

hi,I encountered the same problem about CMake Error at CMakeLists.txt:868 (message):
Could not find headers of used third-party products:
3RDPARTY_TCL_INCLUDE_DIR 3RDPARTY_TK_INCLUDE_DIR FLEX_INCLUDE_DIR
, but I have already downloaded 3rdpaty. I have the header file path, but I cannot find it in cmake
Tue, 10/22/2024 - 13:37
Hello, the issue with spaces. That sometimes can leads to issues. In that case you need just to specify 2 variables manually to include folder
3RDPARTY_TCL_INCLUDE_DIR and 3RDPARTY_TK_INCLUDE_DIR. As for a Flex, please disable CMake variable for "BUILD_YACCLEX". I didn't put 3rd-party for that operation. It is for rebuild generated files. That generation is not recommended to rebuild in case if you don't upgrading functionality.
Best regards, Dmitrii.

I am on windows. i sorted out the issue with OCC executable file, I was using source file.
I have another issue, please help if you can.
When i compile in visual studio i get "Tkernel.dll was not found error. "
Sun, 10/06/2024 - 11:27
Do you compile you own project? In that case probably there are a miss print. Tkernel->TKernel
You can check the CMake sample how to integrate OCCT: https://github.com/dpasukhi/DE_Wrapper-Sample

I am following youtube tutorial in this link : https://youtu.be/i5zCHArA06E?list=PL_WFkJrQIY2iVVchOPhl77xl432jeNYfQ&t=237
he is adding "bind" folder in visual studio environment path . I cant able to find bind folder in newer version of OCCT i believe. path is "..occt-vc143-64\win64\vc14\bind
Sun, 10/06/2024 - 11:50
Oh, oke. I'm not a fun of that channel.
"bind & libd" is a debug libs, they will be generated as soon as you making "install" for "Debug" config. "bin & lib" for Release config, "debi & libi" for ReleaseWithDebInfo config.
Best regards, Dmitrii.

I think i don't understand what do you mean. I am in debug mode, x64. i don't see the folders yet.
Sun, 10/06/2024 - 13:09
To recieve usable folder you need to specify the installation path.
"-DINSTALL_DIR=C:/Program Files (x86)/OCCT". It is a default path. The goal folder will be here. You can update that varaible
Do not forgot to build "INSTALL project in VS". Only after building "INSTALL" the necessary folder will be created. It is not accepted to use result of BUILD_ALL. You need to call "INSTALL".
Best regards, Dmitrii.

I download this link from official website : https://github.com/Open-Cascade-SAS/OCCT/releases/download/V7_8_0/occt-v...
After that i didn't install anything. just extracted the file. So there is no such thing as install folder.
There is no exe file in the downloaded zip. I am so sorry to bother you too much. I am new to programming and visual studio.
Sun, 10/06/2024 - 19:14
The official package from 7.8 have no exe. Additionally that package contains only release version.
Best regards, Dmitrii.
Sun, 10/06/2024 - 22:22
Thank you. i will try to install older versions.
Mon, 10/07/2024 - 10:37
Official packages not delivered in debug mode.
We will start do in November (as a weekly packages).
Best regards, Dmitrii.

Finally managed to get everything work. I am struggling to install qt now. QT is not showing in cmake like others not sure why. I am using opencascade-7.7.0.
I can see other 3RD PARTY PACKAGES. i have QT package also in folders list. but it is not showing in cmake dialog. may be i need to configure something to show it? Please help.
Tue, 10/08/2024 - 11:32
QT will shown in case if you will build one of the module BUILD_QT_SAMPLE BUILD_TInspector.
Only when some components require QT, QT will be shown.
If you need more information, let me know:)
Best regards, Dmitrii.

That worked! :) Thank you so much for your patience and time. I will go through the online documentation next.
I am wondering if you can direct me to some good video tutorials to start with.
Wed, 10/09/2024 - 13:46
Probably there no single place for all information.
My favourite: https://unlimited3d.wordpress.com/author/gkv311/
And you always can check our documentation. Unfortunately it is not so up to date. But you always can collaborate and send us your changes.

I can't able to find solution for the github downloaded files. i will come back for it after you officially release on november. For now i reverted back to old version. I checked some of the tutorials and i am searching more. Qt, MFC are still not working for me in older version (Opencascade 7.7.0) which i downloaded from official website links. i am checking VTK now. if it disappoints me, i see no choice other than AIS.
Please correct me if i am wrong and Many thanks for your help so far. I am new to c++ and visual studio as well. May be that is where i am losing myself.

QT from 3rd party 7.8 s not for reuse. It is only with DLL for eal time.
For reuse we do not redistributed in 7.8, but QT 5 is available as a part of 7.7 package.
MFC working in 7.8 with no issues. Compiled samples available in GitHub page. MFC do not need QT. But MFC had an internal bug for CMake, that was fixed in latest master.
Ar least I have no issues with building.
As for a VTK, you can check it too. All version are supported, from 6 to 9.
As for your issue, I don't know what your log means. Qt5 needs to be used from 7.7 package.
Best regards, Dmitrii.
