Fixing CMakeLists.txt for intel compilers

[landinjm]

Description

project() must be declared after deal_ii_initialize_cached_variables() to properly find the mpi compilers.

Closes #373

Unfortunately, it still does not work.

The Intel compiler is correctly identified. But we still see the following issues:

• The core library still compiles (but only in series)

• The application (allenCahn) produces the following compilation error:

• In addition, if we try to compile the core library in parallel, we get the following error:

icpc: error #10106: Fatal error in /sw/pkgs/arc/intel/2022.1.2/compiler/2022.0.2/linux/bin/intel64/../../bin/intel64/mcpcom

If this is on the login node, there is only 2 cpus and 4GB of memory.

I'd estimate at least 4GB of memory per mpi process when compiling is necessary.
