CMake error while configuration

[FabianAC07]

So, I am trying to build the CMake file but I get the following error:

CMake Error at CMakeLists.txt:5 (message):
  You've selected the 32bit version of Visual Studio 15 2017.

Please delete the cache (file->Delete Cache) and use the 64bit version. (Visual Studio 15 2017 Win64)

Even though, I select x64 over the platform generator.

The whole command window as follow:

Can someone help me to figure out what is wrong?

Hey. I have some issues to set this with VS2019 and MATLAB2018b.

However i figured out this step solution.

FROM YOUR PATH: C:/Users/fabia/Desktop/zed_matlab/zed-matlab/src/CMakeLists.txt

REMOVE the condition: IF(WIN32 AND NOT CMAKE_GENERATOR MATCHES "[a-z A-Z 0-9]*64" ) message(FATAL_ERROR "You've selected the 32bit version of ${CMAKE_GENERATOR}. \n Please delete the cache (file->Delete Cache) and use the 64bit version. (${CMAKE_GENERATOR} Win64)") ENDIF()

SAVE the file and RECOMPILE. Some documentation out there says that now VS select x64 or x86 based on your system. I guess you're x64 so the condition would be unnecessary.

Hi @FabianAC07 , I have updated the cmake file to resolve this issue, can you try it and confirm?

[FabianAC07]

Hello @P-yver,

Thanks for updating the cmake file, but now there is another issue, the cmake file is not finding the MATLAB_ROOT env variable... even though I have added it...

MATLAB_ROOT environment variable not set.
In Linux this can be done in your user .bashrc file by appending the corresponding line, e.g:
export MATLAB_ROOT=/usr/local/MATLAB/R2014b
In Windows this can be done by adding system variable, e.g:
MATLAB_ROOT=C:/Program Files/MATLAB/R2014b

Here the screenshot from the environment variables... I even added it to the main path...

Any suggestion?

[P-yver]

The var MATLAB_ROOT is not an environment variable, it is a CMAKE variable. Have you look to our documentation, you can set MATLAB_ROOT directly with Cmake UI.

[FabianAC07]

Hello @P-yver

The variables in documentation do not appear on the CMake GUI, so I do not know how to include the matlab path...

Same error as my previous post...

[P-yver]

check the Grouped and Advanced checkboxes on the cmake panel, you will see under the title Ungrouped Entries the cmake variable MATLAB_ROOT where you can set your matlab path.

Hello @P-yver,

Thank you very much for the support. It finally worked!

Regards!
