How to compile a single example

[v-dobrev]

If you want to use CMake, Spack will not be very useful -- MFEM's Spack package uses the GNU make build system, for now.

For CMake build instructions, see here:

mfem/INSTALL

Lines 105 to 106 in 9a21f59

	Quick start with CMake
	======================

and more details here:

mfem/INSTALL

Lines 858 to 859 in 9a21f59

	Building with CMake
	===================

Thank you Dobrev,

Are the CMake build instructions in INSTALL for building mfem or also for a single .cpp code?

[v-dobrev]

The instructions are for building the library (default cmake target, all), the examples (target examples), or all executables (target exec) used for testing (these include the examples, miniapps, and unit tests). You can also build individual targets like ex1 or ex1p -- to see all available targets, you can use make help, I think.

I'm clear with it now. Besides this issue helps #1163
Thank you.
