These errors are not related to cmake, but to intellisense. If the compilation gets through, then you can filter those errors out. They are due to the fact that the auto completion plugin was not able to find all the include files it needs. Again, you either specify in the config files the directory where you created the view, or filter these errors out.

Hi, thank you for your message. This has indeed allowed me to run dealii from any terminal without loading spack every time. However, the following error in vscode persists:

An easy way (but it may slow down the startup of your bash terminals) would be to directly add to your .bashrc
spack load dealii
My preferred solution, instead, is to do the following: I create a `spack view` of all packages I need (i.e., just symbolic links to libraries and exectuable), using this command:
spack view -d yes add -i /some/path/to/an/empty/directory/of/your/choice/ dealii mpich (or openmpi, if that’s what’s installed) cmake ninja (gmsh, numdiff, etc.)
-d yes: add dependencies
-i: ignore errors
Then, in my bashrc, I add
export CMAKE_PREFIX_PATH=/some/path/to/a/directory/of/your/choice/
export PATH=/some/path/to/a/directory/of/your/choice/bin:$PATH
This makes sure that cmake sees everything, without having to load dealii explicitly with spack (which may take time, if you do it at every startup).

If you want to be able to compile with vscode , you have two options: you instruct it where it can find dealii (setting variables in the cmake section of vscode settings) or adding the relevant variables to your shell initialization files. If you open a new terminal and you are able to compile deal tutorials without calling any additional commands, then vscode will work.

I think VSCode (or vscode cmake extension) is not able to recognize the environment variable DEAL_II_DIR even when "spack load dealii" command is made from the vscode terminal.

Otherwise you will have to instruct vscode where your library is installed. You can initiate cmake from the command line in the build directory manually, specifying the env variable DEAL_II_DIR. When a cmake cache is present, vscode uses it, and you may be able to get through.
