dynamicCode

[stuart23]

• Investigate the use of libgccjit for compiling user supplied code
• Also look at precompiling the openfoam headers so that they are packaged in one single location and speeds up compilation
• Linking to headers/libs maybe able to be accomplised using cmake properties such as INTERFACE_INCLUDE_DIRECTORIES, therefore getting rid of the need for compiling paths into binaries in the includePaths.H

[stuart23]

Although cmake build is working fine for dynamicCode, there are still some other objects using the old wmake methods (grep -R setMakeOptions *), so the old methods have been left in the dynamicCode obj

Also, optimisation is not turned on for dynamic code yet
